City of Heroes is the only game I've ever come back to. I left Warcraft and all the rest, then never returned. But City of Heroes holds my heart (probably hostage, because of those damned villains!)
However, I wanted to say thank you to the people who make the game amazing. The devs, of course, but also people like @Hyperstrikeand @Sovera, plus the community in the game, who are never without an answer to a question (though sometimes that answer is in the form of some pretty darn funny snark).
So thank you, CoH community, for giving me a home to come back to!
