The Gothic series is really underground but manages to stay a cult classic after many years. Gothic 1 especially , it has you escaping a prison colony, which I think would be an interesting subject for a game dungeon. Blade of Darkness:Severance: a souls-like game that was really good : really nice dungeons, strong combat system and devastating combos. S.t.a.l.k.e.r is a series that while is not mainstream, is pretty much a cult classic so I dunno.
