Data point: Not only do I still play old games, I love old games. I'm frequently firing up titles like Ultima IV and V, Wing Commander, Myst, Age of Empires II, Baldur's Gate, etc. My last Steam purchase was the Atari collection, a bunch of old Atari 2600 and Atari coin-op games from the 1970s, and I've been playing the crap out of them.
I'm not saying that I hope that it's 17 years before City of Heroes comes back, but even if it is, I'll either be dead or playing.
