It's sad when any MMO closes its doors. Just a few days ago I told agentexeider he shouldn't use CoH as an example of how C-Stores are done right because for all we know it might be closing in a month, and now whammy!
CoH had always struggled, though. Superheroes are a niche market in an industry dominated by D&Dish Fantasy style games. I can only hope that some of the CoH players find their way to CO - as I don't want to see that game being the next casualty.
That is sad. But to be fair, 8 years is a long time for an MMO, particularly a niche one like CoH. It fought the good fight for a long time. I hope the CoH players will find a good home with Champs and DUCO, they probably would exist if it weren't for CoH.
