ok ive seen things like this before at events
to take a game & supersize it now i'm not talking an apoc game or anything like that i mean something like BFG where the ships are 12" to 18" long if not bigger on a battlefeild 15'x15' or a medieval sea battle or a team dungen crawler or something like that
i know south london warlords have done it for salute a number of times

well I've been helping to run Living Munchkin at UK Games Expo for a couple of years, and we always get loads of interest in it. Pity we aren't running it this year but I'm hopefully putting on a participation game there!
