Faerie Solitaire is as far as I know the only game I have done that with, mainly because I was enjoying the game and it was easy to play while watching college football games so I decided I would see it all the way to the end.

Alan Wake
Darksiders
Hitman: Absolution
Just Cause 2
Red Faction: Armageddon
Spec Ops: The Line
The Darkness II

The list would be longer if not those damn DLCs.

Dishonored
