I'd like to see a Bulldog style match.
The match starts with 1 archer and everybody else as a naked peasant. The archer stands in a fixed position whilst the peasants have to run from one end of the arena to the other. The archer scores 1 point for every enemy that they kill. All players then take it in turns to be the archer and the highest score wins.
Its simple, fun and much more watchable than archer duels
