I've only binged maybe...five times? Four times? Either way, the ones that come to mind are as following: (Keep in mind these binges were on holiday vacations or long weekends. I don't binge on 2-day weekends or schoolnights.)
1. CoD4 with a full party of buds - we played Search and Destroy as well as Sabotage and RAAAAAAAAAAAPED. Leveled up about...four times? 49, 50, 51, 52. Good times. This is the first binge I think I had. Probably nine hours.
2. TF2. Met some awesome folks online and raped as a Pyro. Six hours I think.
3. Insurgency, again with some amazing guys I was matched with. It was me, some guy, another guy, and a husband and wife. Excellent times killing them Innies. Five hours.
4. Fallout 3. Once I got the game, I fell in love with it. Epic fun trying out different dialogue options and seeing what happens if I kill this asshole, or this asshole, or that asshole over there. Seven hours or so.
BTW, JJJ, GET HL2 AND/OR CSS.
