Heh, well that just reminds me of the man's first session we let him DM. I fortunately wasn't there or i would have possibly ripped my sheet in half just to get his attention.
This is DnD mind you but he shot them up to level 6 or 7 first session after a night encounter of +100 skeletons which gave something like 600 exp or something rediculous like that with only like 10 hp per skeleton.... of course from what i hear he let people use "Rays" as in a line that you could hold out and make an "arc". Like a laser that was on for 2 seconds that you could swipe accross the front of your body and take out everything in the arc of your hand.... <.< Yeah, he's a little cartoony that's for sure. He's come to realize that was a bad move in retrospect and is still learning. I cut him a bit of slack, because it was his first time.
He does make Mary-Sue characters however all the time. And apparently thinks he is the only Lawful Good person out of the group... (when he's actually chaotic but means well XD)
