Alternatively, or in addition to (as I've never quite found this particular style of game);
A story-driven street scum game!
Gang politics, rep building, survival skills, claiming a makeshift clubhouse, mini-heists, street fights involving pipes, chains, and cobbled together guns and handfuls of bullets. Shit getting really really real when you accidentally kill some asshole suit who thinks he can beat on your little brother just because he's SINless. Your best chummer getting in too deep with a narco gang trying to keep everyone fed. Crazy get-rich plans, and building (and fixing) a fortress of neon garbage, scavenged tools, and (eventually) a decent air filter.
That description was pretty inspiring, as things go. Congrats whoever came up with it.
