Other than playing fast & loose with history and mythology, what do you think a game needs to support for a Hercules/Xena game?
Seriously... I want to know. I think most everything can probably be covered, from what I remember of the shows, provided you have characters of high enough level - i.e. Hercules and Xena ARE pretty high level, such that Xena can do those huge leaps and bounce chakrams off of walls to hit things. Maybe there are character definition things d20 doesn't have?
There ISN'T any coverage of Rome, China, or other more outlandish places that Herc and Xena visited, if that's a problem.
