I have almost 2500 hours in the game. There are mods that change the nature of the game to the point where it seems like a completely different game.

There are also modders in the community who have worked on parts of the official DLC.

Speaking of, the DLC massively expanded the game.

But even just the base game is an addictive colony builder where everything is likely to end in flames. Or not. Because there difficulty settings are fairly robust. You can make it a chill little farm sim if you want.

The game is pure freedom.
