GM:
I already hate the dice system they have where you want you to roll low on one die and high on the other two, to make a dumb 616 pun. Basically what I read is if you roll this 1/6 chance a cool thing happens, and if it's this 1/36 roll it's extra cool. And it's not gonna happen but this 1/216 roll will break your game because of how cool it is.
?? With having read nothing else, this one has already lost me right here. Let's not do this.
And I'll go ahead and plug my favorite rules-lite rpg:
The Window -

Don't let the color scheme and the abstract, kind of unsettling graphics put you off (
no idea why they went with that); it's a very non-gore oriented, very open ended & flexible system.
I'd happily kick MHR, or any D20 system aside for this, or something like it.
Among other virtues, it has a means for differentiating super powered individuals from normal level.
