I'm 22(not single ladies, sorry) and I still game often enough, I still play Diablo 2 with my friends, I play Xbox as well, I don't see anything wrong with it, nor do the people in my life.
Now you might have stopped at the Diablo 2 comment lol...yes I still play it often enough with my friends, for us it's more of a social thing than anything else.
We all have girlfriends, we all work or go to school, it's just something we enjoyed doing in our spare time that we still do here and there.
As for Xbox, Cod, GTA and Rock Band are my games, I play split screen or online CoD with my friends, I play GTA because well you know GTA hooker this murder that, and Rock Band has just always been our favorite thing to do thanks to it being so awesome.
And who do I play with? All people around my age, then theres people like my cousin T who is in his late 30s and pwned my ass in Fable 2 and 3, he's Ok at CoD too, but hes got a gaming library at least 10x bigger than mine, oh man he's gotta be the best MK vs. DC player I've ever seen too.
So hes got a successful career, wicked wife, huge house, and still plays damn Xbox like me.
That is awesome, and will never become sad, just like playing video games until you are 75 will not be sad, people just hate.
For the Diablo2 players...
