It would be really sweet for betting to happen before games begin. So I can offer a win, or at least to beat, one or more players, and back that with shards or coin bet. The opponents can chose to accept or decline bet to take my shards (or pay them) upon winning or losing the bet.
Possible Bets:
Winning the Game
Beating the Player
That offer can be sent to one or more players in the game lobby. Ther offer can be accepted or declined. If accepted, the offer is retracted if the player leaves the lobby before game start. Offers cannot be accepted if player does not have the coin or shard to back bet.
This way, I can tell players to put their money where their mouth is.
Problem is, could this be used in ill ways. I believe so.
