I would love to see an airsoft Kentucky rifle. Then we could get exactly 1/2 of the players to wear red and the other half to wear blue. Add in a couple guys playing flutes and drums and we could have a real mil-sim (no G36 or MP5 or ARs allowed).
But better yet, why not an airsoft Winchester 94 and Colt Peacemaker? Then players could don their chaps (not the ass-less ones either) and badges on one side and the other side gets airsoft spears and arrows.
No video game impossible guns there.
