ToW (Tug-of-War) is the best example of a simultaneous move game.

OK, it's coming back to me now...

When IsGameOver is called, the move has already been made and the move has
been added to the moves array.  CurrentPlayer() just does "return
moves.Count() % players.Count()", so to get the real CurrentPlayer()
inside IsGameOver you have to subtract 1 (with appropriate modulus).
For 2-player games, replacing "CurrentPlayer()" with "!CurrentPlayer()"
works.
