Games I've Spent the Most Time On
Whether or not I'd like to play it right now, this is my approximation for each game. Also, this is a sort of relative list, where some games may not have the sheer number of hours dedicated to them, they may be games that wouldn't lend themselves to being played so much (like my absurd time with SotC and Assassin's Creed 1).
