Hero System

The HERO System is unique because it's the only game on the market offering players and GMs the means to create any character they want, and yet keep that character balanced against other characters and threats. It's a point-build system based around the concept of special effects. The rules are written generically, allowing the gamer himself to decide exactly what a power or ability does, and then define it in game terms. For example, you won't find a "Lightning Bolt" or "Wings" power in the book that says, "Here's how you blast people," or "here's how you fly." Instead, the game elements are defined generically. Instead of Lightning Bolt there's Energy Blast and Killing Attack - Ranged; instead of Wings there's Flight.
