This is true only if you're talking about standard rock-paper-scissors, 
which Warp isn't.  He's talking about two-player games of the same 
nature which are allowed to have different rules, and it's pretty easy 
to construct such a game that doesn't allow for ties.  For instance, 
both players show zero or one fingers, if the result is even player 1 
wins, but if the result is odd player 2 wins.  Assuming best play, 
either player wins with 50% probability and there are no ties.
