Okay first off, after reading this, I went in game, and if you ask me, mouse look is perfectly fine for a game with zero combat. (Yes zero is smaller than a small amount). Why do you need fancy mouselook?
I think the idea of moving by clicking a mouse is ludicrous, and err... lazy... Press the keys.
And forgive my bluntness, but what the heck has 1986 got to do with anything? I was one, go me!
Too lazy to edit a file? Don\'t like it, create your own game, or maybe a mod that allows you to change your keys in game...
