Sorry, but I have the strong belief that you can do good role play without combat at all.
I don't know why so many people think that combat is a "must", but anyway, I don't agree to that. Role playing is for me like playing in a thatre, except that you only play for yourself.
Take Hamlet for example, lots of fights, and in the end quite bloody - but the actors still play their role, and that's often without fighting at all !
That's why I'm so against fighting at all : I have often the impression as if monsters are put into a game simply as a means for uplevelling the hero - as cannon-fodder, nothing more.
I want monsters with a culture, with brains, they actually use, with thoughts, but not at all as simple cannon-fodder.
