That's very true. I suppose the GM is kind of the way you progress through a game, directing motion and painting scenery... I've been thinking too much in terms of video games. :P

Interesting! That makes a lot of sense and sounds like it helps with theme/location because it requires a lot of spatial awareness. It sounds like there are lots of number checks involved (though that's no different than DnD, I suppose). How do you keep track of all the numbers? Do you just use stacks of paper? Or would you recommend like a whiteboard or something for the players?

Also, are there specific weapon types that players can use, or can they improvise weaponry and just use logic to determine how they act? Or is that up to the GM, too?
