the issue of a stalemate is always a possiblity, but the true determinate of any game is the commitment of the player(s).
sooner or later the players tire of the game and it ends.
the problem is that most people seam to think that a game is over when they decide its over, this is only the case if that player(s)
is/are the last active one(s) in the game.
if the game takes 6 months to end or a yr to end then who ever is playing it is playing the game they want to play.
sometimes its staying power that is the sole determinate.
and we all know by now theres not much of that in this days twarrior.

I know I personally have no interest in playing a game where all it boils down to is whoever can log in the most consecutive days wins. I've done that once before, it gets boring rather quickly.
