I'm just waaaay behind in terms of Nintendo games right now. I'm playing DQ IX at the moment, still want to go back to Super Mario Galaxy 2 (believe it or not), and I still have to slog through New Super Mario Bros. Wii. On top of that there's Sin & Punishment 2, Metroid: Other M is coming up, and I may pick up DKC Returns as well.
And again, that's just Nintendo systems. There's plenty of stuff on other systems that remains in my "must finish" backlog, like God of War III, Final Fantasy XIII, Gears of War 2, Shadow Complex, etc. And stuff like NHL 11, LittleBigPlanet 2 and hell, maybe even Gran Turismo 5 lurk on the horizon.
I'm at the point where really good games like Bioshock 2 and Red Dead Redemption don't even make it on my radar any more.
