I have more games, but these are the ones I am considering playing that I have to catch up on. Games not listed were either gifts or stuff I tried that I just can't get into and won't likely finish.
Currently Playing:
The Last of Us (single player, taking forever, because my gf wants to watch as I play so we do it together and maybe an hour at a time, sometimes a little more).
PS3 Backlog:
Castlevania: SOTN (finished first castle, mistakenly deleted save file so got to start over)
FFVII (PSN)
Infamous
GTA 4
Gamecube Backlog (got it recently from my brother):
MGS: Twin Snakes
Mario Kart: Double Dash
True Crime
PS2:
GTA III
GTA Vice City
GTA San Andreas
Have all GTAs but only play to mess around with. My brother is the GTA fan so he's beat them all (but not at 100%).
SNES:
Super Mario All-Stars
Zelda: A Link to the Past
Chrono Trigger
Macbook (sorry, don't have a PC rig, though I plan to invest in one in the future, please don't flame me, hehe):
Bioshock
Finish up on Portal 1 and 2 side stuff (beat the main campaigns, but I wanna play multiplayer in 2, also get dev diaries and play on different modes, because I love these two games).
