A genius ruleset that maximises playability, flexibility and mad cap creative fun.
The core rules are so elegant you can have a party of noobs create their characters and get to grips with the basics of play within 15 minutes. However, this ease and speed does NOT come at the cost of limiting play potential - quite the reverse.
Rather than players choosing from a pre-defined menu of skills, characters start out with a loosely defined set of super powers and experiences - which can be ANYTHING they can think of - so long as the games master will tolerate it.
But the best part is the character progression system. Rather than grinding XP to buy from a railroaded menu of advanced skills, characters expand their existing skill set by trying out new applications of existing powers - establishing new precedents for what those powers now encompass. Thus, to progress, you need to get inventive - so the rule system itself incentivises creative play. Characters skills can develop very quickly and in really surprising directions, thus every game within a campaign turns out fresh and exciting.
