I'm looking for a variety of different alternative game ending mechanics/ideas. Not alternative as in 'the game ends in an unusual way' but 'the game has more than one way to end.'
Obviously, the simplest is the checkmate: one player no longer has any legal moves to play, and must concede. Another is (seeing as I've mention card games) one player empties their deck. L5R (the new one, at least; not sure about the original CCG) has honor--accumulate X number of honor and win, or reduce your opponent's honor to 0 and win.
Any other that have you've seen, used, thought of, or discarded (no pun intended)? I'm in an idea-gathering state and some input is appreciated.
