That will only work if you trust each party to follow the same set of 
rules governing the game and not to make invalid moves/cheat, it is far 
better to have a third party (i.e. a gaming server, or maybe one of the 
participants) receiving all the moves and verifying them before 
distributing them to all the players, also a lot of games (for example 
battleships, scrabble, most card based games, i.e. poker, uno) work by 
neither player knowing the full game state with the full state only 
known by a neutral third party.
