I play about 3 hours during the day, then i go outside and play football/basketball with friends, but at night I could play till the wee hours of the morning. CoD4 is just so addicting!
Every once and a while I'll be on all day because there is nothing else to do at all, but normally I'll be on for three or four hours. Then I'll get off and come back on later in the day or at night.
It really depends on the day, but I get a solid 3-4 hours of gaming everyday for sure. Sometimes I'll play DS at work though, so that adds to it and usually when I get home. On my days off I spend most of the day gaming, unless I have plans that interfere.
Right now, 30 minutes if any on the gamecube with my friends. When my xbox 360 wasn't broken though if I wasn't hanging with my friends or anything I would spend 4-5 hours. If I was hanging with my friends I would still sneak in 1-3 hours though
Unless it's wrestling season, then that's cut down a bit cuz of practice
