build your own adventure

While I'm not actually playing it at the moment myself, I hear that the Mission Builder tool for City of Heroes is now in public beta - that is, available on the test server for anyone to play with. This neat little feature will let you design your own villains and small story-arc encounters with them for others to play. I can't say much more about it at the moment, not being personally involved, so I have no idea how it copes with balance issues or players trying to make the All Penis Squad or whatever.
