MMOs tend to shut down relatively often just because there are so many and not enough of a playerbase to keep them all going, especially the super generic ones. CoH surprised me because it's been around for a while (it's a few months older than WoW) and it seemed to be doing fine. The team was putting out new content every 2-3 months, new powersets every 1-2 months. Then to hear that the entire team got axed when they were also working on a new MMO at the time, I just don't get what was going on. Usually MMOs get shut down after they've been in maintenance mode for awhile and the devs/publisher finally decide to pull the plug, CoH was still putting out its best content.
