Community games allow anyone to play a turn that is available, similar to an open chess game in a break room where anyone can walk up and make the next turn.
Specifics:
Once a player makes a move, they are bound to that team for the duration of the game.
All losing teams participants would lose points for the game as if they played a normal game. That would discourage people making bad moves just to grief.
All winning team participants would split the points won evenly.
All player names are logged in the chat as they are now, but the player names in the game would be Team Red, Team Green, ...
Anyone could start a community game
Why it is needed:
There would almost always be a game to play with a turn available
