I used to play alot of games but my problem is that I can't get into it casually. Competed as a 'pro gamer' for a few years then led a few high end guilds and ever since then, if I pick up a game it _HAS_ to be for 3-4 hours at a time or else I don't have fun :( This makes it very difficult to play anything beyond Plants vs. Zombies as every other more complex game saps my productivity and just makes me feel like i'm not accomplishing anything.
