Just hit ye olde 34 last month. Time for games is cut down for sure, but that is due to kids... but as they get older they are playing them now as well, and I am thinking in another year or two (oldest is just about to hit 4) he will be good enough to get online and know how to be effective.
Plus, after about now 20 years of playing online against people, let me tell you, they do the same, stupid, ****, over, and over again, in almost any game.
Sure, some games might be walled off from us as reaction times and energy levels drop like a stone, but there is usually room for predictability and a calm head to still be effective.
I still always am startled when I'm in a game with voice and some dude just blows the **** up when he dies, like, insanity. I'm usually in such a tuned out mellow state it is very jarring when the guy in the same game is so hopped up and intense, but hey, that's youth for you.
