Hmm, ok, I get it. I actually did toy with the idea of having skill sets in the RPG I'm writing now, but in actually cranking through the game mechanics, it turned out to be kind of redundant in conjunction with the other character attributes I wanted to have. A lot of RPGs that lean heavier on skills than stats work out pretty well, though, and are often popular with players.

Anyway, you've obviously thought this through. So why not try to write this yourself? If you've got the passion and the patience -- at you seem to have the former at the very least -- you'll figure out a way.
