Well, seeing as how I'm not going to finish Final Fantasy 13 I should list everything else I'm never going to finish. This list only consist of games for this generation and currently owned. I got to admit, a lot of these games were really bad and don't deserve to be played anymore. Some of them are quite well made. Either way probably never going to finish any of them.
 
Fear 2 
Quantum of Solace 
Motorstorm 2 
Vikings : Battle for Asgard 
Bourne Conspiracy 
Mercenaries 2 
Conflict Denied Ops 
Infinite Undiscovery 
Quake 4 
Eternal Sonata 
Dead or Alive Xreme Volleyball 
Far Cry 2 
Lost Odssey 
Mirrors Edge 
Perfect Dark Zero 
Prince of Persia 
Ninja Blade 
Wheelman

I don't see why you shouldn't finish Prince of Persia. It's not terribly long, and I thought it was really great. I can't blame you for not finishing the others.

Finish Prince of Persia now. That is all.

Mirror's Edge?  You must have a short attention span.
 
And you can't really "finish" Dead or Alive Xtreme Volleyball.

I beat Quantum of Solace in one evening, perfectly enjoyable for a rental.

Still haven't completed Far Cry 2, and probably never will at that. Around 28 hours of the same gameplay is enough for me.  I'm sure I was closing in to the end. Maybe another 5 hours left.

My list of games that I have finished is bigger than that. Does that make you more pathetic or less?

" Far Cry 2  /  Mirrors Edge  "

" Eternal Sonata "

Go finish Mirror's Edge! It's so unique and short, it shouldn't be very hard to finish in a few sittings. It's probably one of my favorite games of this generation.
