Games I've spent an unreasonable amount of time with.
Have you ever invested a ludicrous amount of time into a game? It doesn't happen much. Usually you'll play through the story, have fun with the multiplayer for a while, and move on to the next game. You also probably have a few games you play regularly, in between the next new release. And if you're like me, there's another tier of games altogether. The ones you were so enthralled with that you could not stop playing. The new shooter could wait, you had another 400 hours of Oblivion in you. This list is about those games, in no particular order, and odds are I'll keep adding to it as I remember others.
