Has anyone tried these systems? They are more like generic tool-kits so that people can create their own custom games. They are also skill-based rather than level-based, so a character's power is measured in points. Characters are also built on a certain number of points determined by the Game Master, which allows players to build characters how they want rather than relying on a random dice roll.
I ran a GURPS Lite once, but other than that, I haven't played it too much. I'm more familiar with HERO, although I haven't played it in a long time. I was translating MERP races to HERO long ago, but I lost my notes.
