Except for the fact that Solo and Open are only two of the three game mode options available to players - each player (who has access to multi-player at all) can create a Private Group.SOLO players have access to most of the features OPEN players have access to - but not everything. If it comes to the point where no players play in OPEN, all of these added features for multiplayer would be pointless additions to the game as no one would be in OPEN to use them.
Both Open and Private Groups enjoy all of the multi-player features of the game
