A number of years ago, a group of us felt that there was a need for a super powered role playing system that allowed control of the characters powers and abilities, did not involve extensive use of fractions (although a calculator will be useful), where a character could take more then 50 hits and survive, and where a combat with 8 or 9 characters and a group of NPC's could be resolved in less then an afternoon. We also wanted a system that had more flexibility then was allowed for using D20, but did not require having every kind of die made.
The results are a game that allows the player to create a character with powers of their own choosing, and still maintains a balance so that characters of similar experience will be of similar capabilities overall. This is not to say that all characters are equal, only that very lopsided matches are unlikely between characters of similar experience. Low level campaigns can grow into high level campaigns and beyond. There is no limit to how far a character can advance. And you can create anything from a normal person with a gun to Godzilla, and the only limit is the amount of Experience/number of Creation Points you have to work with.
The game is played using a D100 and 2 D6. Yet characters can do hundreds of points of damage without rolling dice all afternoon.
The combat system allows for the possibility of critical hits and fumbles, which we feel makes it more interesting.
