Re: Longest you have ever played video games for?
I've done quite a few over 24 hour sessions in the past with my cousin on the trusty NES.
I've played through Super Mario 64 and The Legend of Zelda: Ocarina of Time in single sittings several times.
In 2006 a new feature was released on an MMORPG that I played at the time which increased training speed dramatically, I ended up playing the game for 38 hours straight.
The first time I ever played an Xbox360, my cousin brought it over when he was visiting and we played Halo 3 until it red ringed. It was only I'd guess 6 or 7 hours but it felt like a long time.
I really can't game often now that I work fulltime and have a young son to take care of, but I wouldn't mind going on some gaming binges for the nostalgia factor.
