1) You are 3 players
2) The game .. "splits" and you got 2 hosts
3) After split you and one other are 2 players and your friend and someother = 4 players
3.1) "or with you" can mean that you + 2 players and your friend + 2 players = 6 Players?
So if you start a game - the game is splitted - so you and other one are in one game and your friend and one other are in another game - but still in the same game?
