I usually run the game for our group, and every year, we have a Halloween One-shot game. This started from a tradition years back in another gaming group I was in, where each scenario, the players would be playing themselves in some horror scenario.
Every year in the past, I've let players write their own stats. This year, I'm going to have player stats be determined by the average of what every OTHER player thinks they are. For instance, instead of asking a player how likely they are to be able to climb over an 8 foot wall, I'll ask all the other players how likely they think it is. I'm doing this because i have one player that I would call 'extremely overoptimistic' in his views of his own abilities.
