I haven't seen anyone mention Kenshi, so I guess I will.

Kenshi is a post-apocalyptic, RPG, RTS, city-builder hybrid. You can play as one individual character, or you can build up a squad to roam an entire continent full of towns, people, and everything else that wants nothing more than to push your face into the dirt and watch you squirm. It's an intensely brutal game, but one with an aesthetic that I can't get enough of.

There are different races of playable characters (from humans, to hivers, to shek, and skeletons) all with their own different stat bonuses and handicaps. If you lose a limb, you can either find someone who sells prosthetics or just leave that character crippled for the rest of the game.

There's kind of a story, but the game is mostly just you existing in this world and learning about it. There are plenty of different factions you can join or help out, and there will be consequences for choosing a side.

It's also incredibly moddable, with the steam workshop having thousands of mods already.
