Supplement ideas, house rules, homemade stat cards, homebrew weapon types, and other cool variations
Oh, uh, egad, this needed so much work done mechanically. The answer to your questions is on the wiki page: "as per Brikwars." If I remember right, each of those modular squares evened out to about 5 Inches, so you could just fudge movement and range a little by counting spaces on the map like a board game board. I think it would probably have worked better that basic way than the way it was originally set up (see example game on wiki page, original post for link).
