Game series die and do become reborn over time. Look at fallout, it's a game series that was dead until bethesda picked it up. Heck, there is another series out there already being remade by it's fans now, Unreal tournament. And who's making it? The fans, I even knew a few of the big names who are at the top(the community manager, I was for a short time a member of a clan she ran way back). It makes me smile in a sense to see that being done. As arena shooters are seeing a game remade by its fans for it's fans, we are fighting for a game to be obtained and hopefully updated/remade by us, it's fans, for us.
And there are also two games being made by city of heroes players for city of heroes players.
So a comeback is inevitable in some way or another. I'm confident the efforts will succeed and I am hopeful and hopeful the city of titans and Valiance online games will make it. Heck I ponder how much of an inspiration we're becoming for others.
