Is that 3 + GM or 4 + GM?

I can run 7-10 players, I don't know about chaos gremlins XD (I don't even know what they are, I'm just taking a wild guess from the name). I wouldn't want to do it again though, action scenes get stupid x_x and it's harder to manage when you have limelight hogs (not that I've ever had to deal with that before >_>).

_{and I don't even play DnD}

A couple of my current players can probably be considered chaos gremlins which seems to annoy one of the other players a lot more than me, I will tell a player when they're being stupid but I otherwise tend to find the chaos entertaining XD

_{and where appropriate they do get punished for it but I generally try not to kill them unless they've made that nigh on impossible without a serious case of deus ex}
