Wait, rereading Revo's post, I think I misunderstood him the first time. Nothing is stopping half a dozen (roughly) people from bombing all their trial run guesses on just one character.

Though that'd greatly increase the odds everyone else would survive, I see how that can be unfair for the targeted character.

On that thought, I do kind of like Revo's idea of a cap of how many guesses can be made on a character until that character is "safe" (which is what I think he actually meant). Except maybe instead of X guesses a day, it could be X guesses an RP session.
