It's a very detailed game, but for me, it was just too hard/complicated.

The graphics were fun and it was good for a few hours, but as others have posted, to figure out any of the complex systems, you have to use YouTube/Reddit/wiki, etc. I'm ok with that for advanced strategies/gameplay, but for the beginning/midgame, I would like to be able to figure it out inside the game.

Some the controls are a bit wonky. To upgrade something, you have to delete then rebuild (vs. just upgrading the item). In my play through, I upgraded a bunch of wires. Turns out that I didn't have enough material, so somehow the existing wire / electrical grid stopped working, I didn't notice, everything stopped and everyone ended up starving (I had some heating issues too). I know some people love this type of harshness, but not for me.

So, for me, just too frustrating. I'm more into other base-builder/survival games: Factorio, Satisfactory, Captains of Industry, Timberborn (in that order) are all lots of fun ...

Teaches more than most subjects in school.

I finally made it to space, wasn't as hard as I thought. 10/10
