Yeaaah, knowing you're into RPGs and random indies, I'd recommend JRPGs, and if you already have any JRPGs I'd add VNs. Certainly the options involving less high school relationship drama, which is why I say that the
specifics are an issue and that 90% of everything is crap, but, well, there are some extraordinarily good non-teenage-relationship-drama stories out there in JRPG and VN land.
Some recs in that direction, based on what's presumably a collection of western RPGs and FPS games: Baten Kaitos (gamecube), Most Final Fantasy games in the single digits, Golden Sun I and II (gameboy advance), Umineko (PC), Steins;Gate (PC).
