Just to reiterate: this thread isn't really about numbers of rules. it is about presentation, clarity and conciseness. You cna do chase rules in 100 words. You can even do Luna Rule Futbol in 100 words if you want.
I love clarity and conciseness. I also think that's a very hard challenge. In 3e D&D people seemed to think that writing a new feat was the easiest thing in 3e D&D design because they were short. In fact, because they were short writing a good feat was one of the most challenging things you could do in D&D design, and 3rd party publishers and even WotC wrote a lot of terrible feats.
So let's see it. What would your 100 word chase rules look like. I'm not saying you can't do it; you may be a much better rules smith than me. I'm just saying I doubt I could write a 100 word chase rules for any game system that would in general case be a better approach than handling the scene by fiat or which would really provide clear guidance and useful support to a novice GM.
