Much like tynstar, I sometimes game more in a week, and then nothing the next.
Afew years back, I was doing 25+ when I was playing Phantasy Star Universe. I also played a ton of Halo 2 online.
Of course this fall with Phantasy Star Universe coming out, I suspect I will tend to play a bit more
I dont even want to talk about PSO it makes me tired thinking about how much we played.
