I think it boils down to this:What's your favorite crunchy game? What kind of crunch do you like? Is it okay for a game to be crunchy in one area and not in others? Preferable? If you don't like crunchy Games, why not?
That really does not describe any game of RoleMaster or GURPS that I have played. While being very crunchy they are also very permissive.In crunchy games, the GM usually tells me, "you can't do that."
