I'm a bit over thirty. Unfortunately, unless a game really grabs me by the collar (doesn't happen as often as I'd like) I just don't find as much time to play games as I used to. Various responsibilities, possibility of child or spouse interruption, need for sleep. Mostly these days I play my DSi or flash games that I can leave at any time without too much regret. Prototype is amusing, but it hasn't really captivated me enough to really hit it hard. Looking forward to Mass Effect 2, though.
I really miss some of the good teams from games like Team Fortress Classic- when a group of people clicks in a team-based game, it's fantastic. I just don't feel I can play a game where other people will count on me for the quality of their experience any more if I might have to drop out on a moment's notice. Doing that is only half a step above griefing in my book.
Mostly my time on the computer these days is spent on my own creative projects. Which does include creating a couple of small games of my own, though.
