So im torn. Im recommending cause there is long term play value even though was released in 2023. SOme major needs are a start tutorial. The AI seems to work very well but some of the issues are the constant clicking just to mine one thing at a time and then it gets overhwhelimg to figure our whats needed for what because things happen totally out of order. But i still
recommend.

So some of the issues include running out of resources to make more items before you even get to the planet. This doesntmake sense considering the QUANTITY of items under the planet and the ability learn new things doesnt happen till after something else so the balance needs to be adjusted.
