The impending shutdown seems to have stirred up some activity on the emu front. Here's a utility to export your characters from the game... y'know, in case down the line you can import them somewhere else.
"At midnight Pacific on Saturday, December 1, NCsoft shut down the City of Heroes servers for the final time. Since announcing the closure, a group of players has been working hard to revive the game by getting attention from the gaming press, recognition from celebrities such as Sean Astin, Neil Gaiman, and Felicia Day, and assistance from fantasy author Mercedes Lackey. Meanwhile, NCsoft has been drawing negative publicity, including a scathing article about the shutdown from local news site The Korea Times, noting that the game was earning $2.76 million per quarter and that 'it is hard to comprehend what NCsoft means when they say they closed it for strategic reasons.' NCsoft's stock price has fallen over 43% since the announcement in August, almost 30% below its previous 52-week low, right when investors were counting on the success of the recently launched Guild Wars 2 to help boost the company."
