[@Dread] The best one that lived for years that I was apart of was more communal than having 1 GM. While the GM held the mysteries and shit, the plot, world and characters were developed by everyone so everyone had "a say" in the RP. Funny thing is, it was only 3 of us because the original had like 15 players then boiled down and in the end there was the trio. Great fun. So maybe the size is a factor in the life of the RP. The only reason it died was because I left/stopped coming to RPG. Now that I'm back, the other two seem to have been gone for some time. I don't know if we'll ever bring it back to life.
