Something we used to back in the day......kinda similiar to this and can be done nightly
get a room full of UF peeps....appoint 2 "captains"
they then pick from the pool of players in the room to form a team.
then the 2 teams play each other. Whoever has the highest score/ or lowest score on each team at the end of the map would then be the next 2 captains.
It takes a little time in between maps to get the teams picked every time. But its fun ! !
