Someday, I need to run a campaign that actually uses these ideas. Or just get a copy of Mutants and Masterminds.
Though I think there is something to the "Dungeons and Dragons rules, superhero attitude" idea. This may be something to try with The Book of Nine Swords.
Or--actually--with Iron Heroes. Though I have a suspicion that the two systems may work fairly well together. Might take a bit of tweaking.
I wrote those notes during the two weeks I thought Exalted was "totally awesome." And the six months when I accosted people with Batman factoids on an hourly basis. Can you tell?
