By ground level, I mean games where the scope is of people on the ground (either an individual PC or party) rather than playing as an abstract nation or political party like in a grand strategy game. So nothing Paradox- or Kremlingames-related (though, Victoria 3 including little things like pop info is a nice touch).
At first, Fallout 4 seemed to fit the bill with its settlement system but it's still very much within the bounds of capitalism and private property no matter how much I like to think the Minutemen are actually communalists or whatever.
Rimworld might fit the bill? It's not as top down as paradox games, since each colonist has their own personality and needs. With mods you can have leftist ideals in your colony, and fight against an oppressive empire. The latest expansion probably won't add too much to your intended playthrough, but the previous three could very much add to it. Biotech arguably less so, unless you want to make superhuman soldiers for the revolution.
