I was playing The Orange Box, but now I've gone back to Halo 3 for God knows why. I just keep doing Forge and Matchmaking.
And before The Orange Box I was playing FFIV, which I also still need to finish.
And before that was GTAIV which I cannot seem to get into no matter how hard I try.
And before that was Okami, Mario Sunshine, Resident Evil, Metroid II, OoT Master Quest, and I bunch of other games I haven't got around to finishing...
