i posted something similar on the espionage board

4 players playing battleboats, 2 players per team, 2 teams per game
(maybe less ships per player)

players are allowed to communicate, teammates can discuss their tactics (as in real life 'battleboats')

first player 1, (team a), then player 2 (team b), then player 3 (team a), then player 4 (team b)

as soon as all shops of 1 player have been sunk that team loses and the 2 players of the other team win. each player gets his bkr adjusted individually

what problems could there be ? (aside from the problem of 4 players being able to use more time before everyone has made 1 turn)
