Right now I can proudly say that I only own three games that I haven't beaten in some form or another (whether It's 100% completion or just a basic playthrough of the story mode)

1. de Blob: Bought it, opened it... but somehow I never got to play it. It's only a matter of time before I give it a go.

2. Sonic Unleashed: Was one of many Christmas gifts, and it got lost in the shuffle. I'll get back to it sooner or later, seeing that the daytime levels are too much fun.

3. Phantom Hourglass: Beat the first temple, sailed to the next island... and I haven't touched it since. I have no idea why I stopped playing the game, but here we are.

I got Killzone: Liberation for free, but I haven't played much because I need to get all the gold medals on WipEout Pure. I'm at 116 I think.
