Stole this thread idea from another forum I frequent.
Like the title states what games do you have that you have not completed.
I have loads of games I actually sometimes buy games and never even play them, yet I will still get the DLC for them. Completionist maybe.
Here are just a few, some of these I have not even started and some I have not finished.
Skyrim (not finished actually only made it through the first town where it starts.
Fallout 3 (not finished)
Fallout New Vegas (not started)
BO2 campaign (not finished)
STALKER (all, not finished))
METRO 2033 (not finished)
Tomb Raider (all to include the newest one, all started and not finished except the newest one I have not started yet)
Dragon Age Origins and DLC (not started)
Assassins Creed (all, some started but none finished)
Prototype 1 and 2 (started both but never finished them)
Civ 5 (not started)
Space Marine (not finished, not my fault though as the PC version was so buggy I gave up)
Transformers WFC (not finished)
Uncharted 2 (think I started it but meh)
Those are just the ones I have off the top of my head. I am sure that there are at least 40+ more titles I have not finished or started.
