I would like to make up the first official "well, make it up yourself" club.
Anyone wanna join?
Since I made it up, I get to be President though.
Seriously, I see this disparagement of creativity all over this board. There are far to many left brained individuals who seem to have the underlying belief that if a solid mechanic isn't set forth for their idea, factory ready, its meaningless. . .or that everything THEY can imagine must be covered under the rules, as if some unified theory of roleplaying will emerge granting the game a para-real existence.
My imagination is bigger than the rules. All imagination should be. The rules just give me a basic skeleton to build on. So make it up, suits me just fine. YMMV, and clearly does.
