Ok then, get shit done time...
I'm thinking such a game would have to be full team Volleyball, six units per team arranged in a three by two grid pattern...
Each turn would allow a player to pass the ball up to two times for bonuses before sending it over the net on the third hit.
Unit stats would probably be Ballistic Skill, Toughness, and a Receiving Save...
...Damn, we need a /sp/ anon in here, I know at least one team rotates positions on each serve, but it's been a while since my sister played in Highschool...
