Just Cause 2.
Although it wasn't really the story that stopped me playing, it was more the fact that you could access all the fun features of that game from the very beginning (all the crazy grappling-hook-parachute-etc. shenanigans), hell, even just from the demo so there wasn't much point buying the game in the first place. So really the only reason to play the missions would be if they had a really good story to keep me interested. Sadly, that was VERY MUCH not the case. So I just fuck around after the first couple of missions permanently now.
