User blog comment:ChishioKunrin/How much work would go into a RWBY MMO?/@comment-25405817-20150912001647/@comment-25396609-20150912002117

City of Heroes, complete character customization, extremely fun, first MMO to include player generated content, plenty of sues, yes, but just as many awesome characters.

I only played for a couple months not long before they shut the game down to make room for Guild Wars 2 on their servers.
