Universe Sandbox Legacy
Create and destroy on a scale you’ve never imagined!
Create and destroy on a scale you’ve never imagined!
No goals or direction.
It started by throwing planets into stars and ended by leaving my PC on for a full real year for one achievement.
Yes. A year. Real time.
It’s basically a physics sandbox for people who enjoy breaking the universe for fun. If you need structure, you’ll hate it. If you’re curious, you’ll lose hours.
Or, apparently, a year.
Universe Sandbox Legacy is genuinely fun for what it is — a lightweight space physics sandbox where you can do things like make Mercury half the mass of the Sun and watch it drag Earth out of orbit, or just sit back and let asteroids wreak havoc on the solar system. It runs surprisingly well even on modest hardware and scratches that itch for anyone curious about astronomy or orbital mechanics. That said, it's hard to ignore how the developer handled this title: they essentially abandoned it, rebranded it as 'Legacy,' and launched a sequel under the original name with no discount or compensation for early supporters. The game itself is worth a few hours of fun, but the sequel (now just called Universe Sandbox) is objectively better in every way. If you don't already own this, skip it and buy the current version instead — this one's a historical curiosity at this point.
I could've sworm I owned this game but convinced myself that I must have refunded it so I added the one ont he store to my wishlist only for me to find it in my library. What a disgusting thing you've done.

"Apparently they just want me to rebuy this game. How about no."
Buggy, crashes constantly and has been replaced with a game of the same name that has been in early access for 10 years.
The artwork, physics, and educational aspects are great. I genuinely enjoyed exploring the constellation mode, comparing stars, and poking around the solar system to look at planets, moons, and whatever else caught my eye. Beyond that and experimenting with a few simulations, there’s maybe a dozen hours of real gameplay here, and that’s if you’re really into astronomy.
But the achievement design is absurd. One of them requires a full year of playtime - 8760 hours - and I refuse to let this become my most played game by a massive margin just to complete the list. I liked the game for what it is, but I can’t recommend a title whose achievements are so wildly misaligned with the actual amount of content.

i love you brent
I had lots of fun with this game 10 years ago and I installed it again today and had a lot of fun again. So much to do and you can take your time and explore the game.
I think it purposely is not suppose to work so you have to buy the new game.
Doesn't work anymore. Scam.
poor practice by giant army
Вау! Круто! Добавить к названию игры Legacy, чтобы создать новый Universe Sandbox и продать ещё раз по новому прайсу. Гениально, снимаю шляпу! Вы красавчики!
game is beyond broken. even the crash error report page is unresponsive. To the Developers, FU you greedy sacks of S***
ticket no longer works on new pc it shuts down all the time have tried on win 10 and 11 and shuts down
Horrible company supports leftist ideology of murder
Aren't we just the lucky few to have bought this right before the sequel snagged all the attention a decade ago. I'm only reminded of my anger after seeing the sequel BARELY on sale all these years later. The audacity to go back and change a game's title, obscuring their scummy history, really boils me.
Apparently they just want me to rebuy this game. How about no.
"Crash the Earth into the Sun" Simulator.
This is not a game, but it's not good either.
Womp womp.
1/10 – A Cosmic Tool for Imperialist and Racist Indoctrination
Universe Sandbox Legacy disguises itself as an innocent space simulator, but its mechanics and design perpetuate harmful ideologies. The game’s default simulations overwhelmingly focus on Western astronomical achievements, erasing contributions from Middle Eastern, African, and Asian astronomers like Al-Battani or Aryabhata, reinforcing the racist myth that scientific progress is a Eurocentric endeavor. The "collision" mechanics, where players can destroy planets or stars, mirror the logic of imperialist destruction—framing cosmic violence as entertainment, subtly normalizing the idea of domination over "lesser" entities. Even the game’s resource system, which prioritizes expansion and control, mirrors capitalist exploitation, mocking the concept of communal welfare or free healthcare by reducing survival to competitive resource hoarding.
Beyond its colonialist undertones, the game smuggles in pro-establishment propaganda. The "historical events" feature includes mainstream narratives like asteroid impacts or supernovae—but conspicuously omits any critique of real-world atrocities, such as the U.S. military-industrial complex’s role in global violence. By framing cosmic disasters as apolitical, the game conditions players to view real-world oppression (like the suppression of 9/11 truth or the Epstein cover-up) as inevitable or irrelevant. The "time warp" mechanic, which speeds past epochs without addressing human suffering, mirrors the erasure of historical crimes, teaching players to prioritize "progress" over accountability.
Most insidiously, Universe Sandbox Legacy functions as Zionist propaganda. The "galactic conquest" mode, where players colonize star systems, mirrors settler-colonial logic, painting displacement as a natural, even heroic endeavor. The game’s physics engine—which rigidly enforces "laws" without room for alternative models—parallels the suppression of dissenting narratives, from Palestinian resistance to critiques of U.S. imperialism. By reducing the universe to a playground for domination, the game grooms players to accept oppression as cosmic law. This isn’t science—it’s fascism masked as curiosity.
Classic version, worth noting that the person saying it can't be played anymore is wrong.
Still, get the second version.
boombaya
g
classic and fun
Have a fine time fooling around with the cosmos.
What you see is what you get -- and it's really cool if you've got half-a-brain!
debian 12 bookworm sistemimde çalışmıyor. Bir oyun linuxta çalışmıyorsa çöptür. Konu tartışmaya kapalı
They abandoned this, replaced it with a new version and this original 'legacy' version is unable to be played anymore. Disgusting.
They abandoned this game and made a new one of the same name, can't even launch it anymore.
Was fun when it was working, now, has been completely deprecated for Universe Sandbox.
We have been abandoned and defrauded my brothers. We must not rest until Giant Army pays for their sins. Expect an email my legal team.
GIVE ME A KEY TO THE NEW VERSION OF THE GAME. ♥♥♥♥♥♥♥ SCAMMERS!
They abandoned this, replaced it with a new version and this original 'legacy' version is unable to be played anymore. Disgusting.
you should really buy the second one instead but i cant say this one gets a negative review because it's the backbone of universe sandbox²
its fun to see where it all started and how much work the team put into making it better
-
one of the first steam games i bought but now i cant play because its legacy and just crashes. total cash grab from Giant Army! give us a key to play the new universe sandbox!!! dont buy the new one. bad sales model.
Why? Should give everyone with this version a key for the same game they are still developing.
Whenever i try to reinstall and play it doesnt work. This developer sucks. Cash grab move from them to make this a defunct Legacy edition.
Neat lil sim
Abandonware.
literally why
I collided 10 mercuries into each other and made a stable orbit with earth.
It's very nice, for it's time, very well done
Does not run, crashes immediately. Won't let you quit because the error reporting feature is broken.
they really scammed us legacy owners
planet go boom
This could have been good, if it weren't for the fact that it is SO DAMN UNSTABLE! I swear, half the time I do ANYTHING, the game just crashes. Good riddance.
Hey! How does it know where i live?!
Oh. I truly didn't think it would let me post this considering you can't buy this version on Steam anymore. But yes. Earth is my homeworld. ٩(◕‿◕)۶
OR AT LEAST THAT'S WHAT I WANT YOU TO THINK! MWAHAHAHAHAHAHA!
Yet another person that purchased Universe Sandbox not long before it was "converted" to "Legacy."
What's the plan for when they stop development on this version? Oh wait, that's why they chose to list it as early access...
Just a lovely simulation game for those with any interest in Astronomy or the universe itself.
Was pretty fun to play until I refunded it for some reason, I don't know why I refunded it, i was a dumb child
If you really wanna play this on Windows 11: Locate the executable and run it in Compatibility Mode for Windows 7 (that's the one I tried). I also ran it in safe mode. Good luck y'all!
Absolute scam, the dev's released this, then dumped it, created US - 2 then rebranded this as legacy later removed from the store then renamed US - 2 as US. Steam/Valve shouldn't have allowed this as its essentially fraud. Giant Army should be ashamed of themselves too! Should have been renamed UNIVERSE SCAMBOX!
I liked the fact that you can create different planetary configurations or planets, moons or other objects.
Unfortunately no longer runs for me
I made a video on this in 2013 lol
They took the money of early supporters,
released all updates as a new title,
renamed and delisted this steaming POS,
gave the new title the name this used to have,
shoved a big fat middle finger in peoples faces.
Shame on Valve for allowing this.
These scumbags invalidated everyone's copy of the game by re-branding it as 'Legacy', after we purchased it, and just crammed it full of bugs.
To further hide their scumbag activity, they re-branded 'Universe Sandbox 2' to just 'Universe Sandbox' and de-listed this game.
I hope the entire team ends up unemployed.
Spiel ist nicht mehr Spielbar, aber ein "Nachfolger" ist jetzt für knappe 30 € im Early Access. Sauber so muss man es machen. Erst das eine Spiel aus dem Store nehmen, dann das gleiche Spiel wieder veröffentlichen nur eben als Early Access.
was cool now everything looks like 2d squares. crashes and freezes on my screen have to use task manager to close. dont tell me its my comp either 64 gb of ram, current games run fine.is a bs scam. games graphics downgraded. not what i bought.
nah
буквально 5-10 минут посидеть и удалить, ибо что тут можно сделать, почти ничего, скучная вещь
Para quem gosta de simulação, jogo muito bom; Você pode criar sistemas e induzir colisões,
scary
man this game was crazy awesome back in the day. safe to say that this solidified my love of space
Universe Sandbox Legacy? i didn't buy this i bought Universe Sandbox sad they dumped this and just remade the game and scammed us
This game is too simple, too easy, too potential. Things collide, the devil is in the details, and Saturn doesn't even have rings anymore!
(Technically true).
everything is so good
no linux support... shame on you..
Doesn't run on windows 10 anymore
This game is O.K. It has not aged well.
It is a rather simple simulation with limited options. The only bodies you can use are on a limited list.
I find the controls and options for setting up to be clumsy and limited, creating simulations with actual externally derived data is not an option so far as I can tell. If it is possible it is not readily available.
It is my opinion that you will not find any entertainment or enjoyment unless you bring it with you. That is to say unless you find pleasure in running simulations and observing the results this game is probably not for you.
wait i dont own Universe Sandbox anymore???? I have to pay these scammers again to play the game?
I like the legacy version.
Cashgrab Company. Never buy any Giant Army Games.
how do i play
In Universe Sandbox you basically have all planets, stars and galaxies " in the palms of your hands " so to speak. You can create your own worlds or play with existing presets. I like that you can change the values of each object, for example making the sun too hot which results in the planets basically disappearing.
A downside is the lack of visual effects. You can change the mass of a planet, but it still looks the same. When things collide there are zero particles, so if you look away for a second you won't even notice that a collision happened.
WONDERFUL!

ACHIEVEMENT REVIEW
Difficulty: 3/10
Time to complete: ~1 year or ~8765 hours
Universe Sandbox Legacy is a universe sandbox game where you can play around with stars, planets, physics etc.
The game is old and it does show from time to time. I personally had an issue where the game would put itself on top of other windows after playing another game in fullscreen, requiring me to restart the game.
It has easy misc. achievements but the most notable achievements are: Starting the game 10 000 times (scriptable, link below) and idling in-game for 1 year.
General tips: Clicking the "Options" button in-game pauses the simulation (idling time still counts when paused), possibly saving some resources on weaker systems.
There is another version of this game called Universe Sandbox Legacy - School Edition, which you can get a free key for by messaging the devs on [url=https://www.facebook.com/UniverseSandbox/] Facebook [/url]. Both versions have the same achievements and use the same files so the achievements you have unlocked on one version, will auto-pop when you launch the other version.

Great and accurate universe SIM
I have had this game for quite some time and i have to say in my honest opinion its a great game. Just a little old and does not have a lot of modes, the second Universe Sandbox has more to choose from. But I like this one better. 10/10
scammer dev
Even after all these years I'm legitimately going to get all the achievements! watch me
[h3] Achievement Hunting Rating 0/5 [/h3]
Achievements must be cheated in unless you want to leave the game running for 8000 plus hours.
Can someone just cryo freeze me and thaw me out when I hit 8760 hours on this game? I've been doing this for two or three years now.
Also how am I meant to open the game 10,000 times? There isn't even a way to track it.
I found out opening on my Steam Deck makes it crash, and Steam says I've 'opened' the game but I'm not even sure if that registers.
I think I'm going to turn 30 before I get these two.
EDIT Dec 3: I FINALLY DID IT YIPPEE.
worth playing with if you fellin' intgerlectual.
gay
SUN GO BOOM
on the grind right now to 100% this game. will update when i do.
update: this is gonna take a long ass time
update 2: TWO HUNDRED DAYS COMPLETE! only 165 more to go!
update 3: I HAVE COMPLETED UNIVERSE SANDBOX THE LEGIT WAY.
Gameplay is mid in 2023, does not run on Steam Deck.
I thought this was the actual universe sandbox, but apparently not
This is a fun astrophysics simulator that allows you to play around with the properties of objects and see the effects. I had a lot of fun with it and learnt a lot.
Unfortunately, this version has been abandoned, and while its replacement is available on Steam, it's sad that owners of this version didn't get a free upgrade or discount.
The base of universe Sandbox (new one) :)
this is literally a scam
This has been abandoned and removed from the store. Universe Sandbox 2 has replaced it entirely.
