Adventure games... I probably play them more than RPGs these days (well, because practically all games are Adventure games, now days). Assassin's Creed, Bioshock, Metroid, etc. They typically have pretty much all the things I really love about RPGs, sometimes more. I love side scroller Metroidvania's too... without the "vania" (never was much into Gothic vampyre stuff). What can I say? I'm a Metroid super-freak.
Thanks Ninja, for killing my favorite series.
