I'm 46, and CoX is the only MMO I have ever played. Never felt called by any other game. Lifelong comic book nerd and CoH was my dream, wish, fantasy fulfilled.
A friend introduced it to me (Issue 1), and I bought it right after Issue 2 came out. Played until close to shutdown when I realized I wasn't in a healthy place playing the game (too much time online, not enough time spent in RL). So I never jumped into Champions, Marvel, or DC's MMO's
Never played one since. I saw on Easter a friends posting about something in a facebook group called CoH Survivors talking about big "reveal". I waited 2 weeks just to be sure NCSoft wasn't going to shut it all down right away, and now I am back.
I'm still in a good place right now with the appropriate balance, so hopefully that sticks around...
Anywho, that's my MMO history
