Centurions would kick their asses.
OK, how about we get a ton of sports people, and put them in this big arena, and they're allowed one weapon, but some of the weapons are booby-trapped and blow up unexpectedly, and then they have to run around in the woods, and there's genetically engineered wasps and shit, and then a couple of them would get amorous, which quite frankly is likely to be a bit disgusting with NFL and soccer players, and eventually one would make it all the way through and she'd shoot Donald Trump with a crossbow right in the middle of his SOTU address of his second term?
That would be fucking great!
