My gaming sessions have definitely shortened and my attention span for games has lessed on the whole. I used to be able to play for 5 or 6 hours straight but now I play for a little bit, pause it and go do something else and come back or I just play for a hour and turn it off. Rare exceptions like fallout 3 aside where I can still play for long periods of time still come around but they are few and far between.
Agreed. I can't sit for more than a few hours at a time playing games now, if even an hour. The only exception is Dragon Quest. I dread to think of all the time I'll waste on the MMO whenever it comes out in the US *Shudder*
