I think an option to prematurely end games might be a nice option, like, if one player could propose a draw or something of that nature. I'm not sure if or how it might be abused, but i think it could definitely be used to save some people some trouble. Me for instance
I jumped into a game with one opening hoping to just get started right away, and where i found myself was in a game with three friends who were waiting for their fourth, but alas, i found my way there before the lost friend. Because i was not the desired competitor, my three opponents decided to not play at all, and therefore not take their turns, so i'm left with a game slot taken by one in which i can hardly play. Hopefully my plan to take one of them out before going deadbeat comes to pass though
Back to the point, if they didn't want to play, and an end game option existed, i'd be brimming with action packed conquering, and not settling for a mesely three games. I guess i could just get a premium membership...but thats beside the point.
