(Since I'm now a mod here, I guess I can add something ^.^)
There's also another form of RPGing you can use - story-based RPGs, which don't have a Game Master. In this case, the person who starts the RPG just makes rules for it, not decide the outcome of all fights; however if problems arise, whoever started the RPG is still in control.
Final note: It should be obvious to everyone, but this is for roleplaying. General discussion will be closed or Swamped
