The current /duel commands work very well, however they could be fleshed out a bit more. I think a betting command should be added. So when you challenge a player you can set a bet as well. You would not have to set a bet obviously if you did not want to. The challenged player would see something like this...

Durgia has challenged you to a duel! He has bet 10000 credits on the fight. Type /duel accept Durgia to start the duel.

Then whoever dies first or quits etc would have the bet amount subtracted from their credits and added to the winners. If a player does not have enough money to pay there should be some penlty or just make it that you cannot accept the duel unless you have enough $$ to cover it.

Anybody with other duel related suggestions feel free to add them on, and critism is always welcome if its constructive!

Good idea Durgia :)
