It's good but steep learning curve with a lot of things you'll spend learning outside the game. Fully socialist economy means you'll be collecting resources and turning those resources into industries in order to do build society, provide jobs and so on. Instead of just zoning and leaving things up to the market. This obviously has a lot more complexity though as you learn exactly how all the chains work, how vehicles are managed to do logistics across all the chains, etc etc.

Once it does all start to click into place it's rewarding though.
