I'm almost 27, and I've more or less stopped gaming. It's not actually that I don't have time, it's that... I have too many games?
It's really weird. When I was little, my brother and I would play through Super Mario World or Final Fantasy II over and over again, because we were little and really only got new games at Christmas and birthdays, and usually only one. We had one active system (SNES, later got a 64 when they came out) and so there were really only a limited number of games - so games were great and exciting.
These days, I have a major backlog of games that I mean to play, and getting started on them just seems daunting, more like a chore than a reward.
Guess I'm getting old. Ah, well. You young hooligans stay off my lawn, now, y'hear?
