currently, in "my games," the games are sorted by the time that the current player has left to play. but, this really doesnt tell you how close you are to actually playing. why not automatically put games in which you are next to play on top. you can sort within these games and within the remaining games using the current method. obviously, this isnt perfect, but would give you a better idea of which game you will be playing next.
EDIT: by "next to play" i mean those games in which one player still has to act before its your turn.
