Guilty as charged. I have so many games sitting in the cabinet that haven't been finished or in some cases even opened.
I buy games with the intention of playing them when I finish my current title, but then something sidetracks me (currently the OcUK Fifa League) and I never get round to playing them, or a new title comes out that I have been eagerly awaiting, and they go further down in the queue.
The last game I completed I believe was COD4. I have Burnout Paradise (played for 2 hours) Lost Odyssey (still in wrapper), Assassins Creed, NFS

S (still in wrapper) to play a large amount of.
Not to mention the games I have played for considerable time but not finished, again, blame Fifa and COD4 online.
Then you have the soon to be added to the collection titles: Viking, Condemned 2, RSV2, GTA4, MGS4.
