Have any of you ever taken part in one? Helped to develop one?
How much information is generally needed by the GM's in order for it to be successful?
I'm considering starting one of these up and I'm just trying to figure out if I give a GM a dossier for the group with some basic intel, as well as some GM specific information on opposition (troop numbers, equipment, stat blocks, etc) if you think as a GM that you could make it work.
The less I have to do per group, the more groups can be accommodated.
Further, the more involved you are in the developing phases, the easier it may be for you to run.
Thanks for the help, and hopefully potential interest.
