I have this problem, I still need to finish Lost Odyssey, Oblivion, and Bioshock, plus I just bought GTA 4. This is another reason why I don't want to get another console because I'll have a lot of games I won't finish.

Currently, I am playing GTA IV, which will keep my occupied for ages, but I still have to get back to Star Ocean 3, Burnout Paradise, Gran Turismo 5 Prologue, Rainbow Six Vegas 2 (online modes) replay Uncharted and FF X. I also want to get a 360 with Lost Odyssey and Ace Combat 6 this summer... I need more time!!!

I sometimes have that problem, but I usually decide to just buy one game at a time. This way I get to focus completely on the game and I sometimes get lucky that I can catch a game on sale or after a price drop.

I've managed to avoid this on the DS so far, but these are the following Wii games that I have not yet been able to even begin playing: Godfather, Scarface, Tomb Raider, Medal of Honor Heroes 2, Geometry Wars, Battalion Wars II. Also haven't finished Mercury Meltdown Revolution, and want to buy a handful of others.
