I miss 3D mascot platformers (Ratchet & Clank, Klonoa, Sly Cooper, Crash, etc). With the exception of remakes/remasters of the old stuff I can't recall the last time new one that was really great came out.

I also miss fighting games. I mean they're there, but I find them hard to jump into these days. I think SoulCalibur IV was the last one I played for for months on end rather than playing for an hour or so before deciding it wasn't my cup of tea.
