The next issue of City of Heroes will include a feature called Mission Architect, which will allow players to design their own original missions and story arcs to share with other players. More info found here:

I used to DM old school AD&D back in the day, and I've been wanting to get back into creating adventures. It sounds like this feature will provide an interface to handle all the bytes and pixels and such, leaving the designer to concentrate on the storyline, enemies, objectives, etc. I assume it will be available on Red Side as well as Blue Side. Not sure if we'll be allowed to insert our own toons as NPCs....
Anyone else looking forward to trying their hand at mission design?
