We used a dice system to determine hits and misses in playing beer pong in a different group and it seemed to help and added some humor. We did it to ensure no one was like...super all star beer pong champ and slammed all the cups. Nothing extreme like stats or anything, just a determination hit or miss to add an element of surprise when ya post. It worked pretty well there so I figured it could be used again or people can work out how fights may go before initiating too.
