this may be a silly idea, and perhaps itbelongs in the dead horse thread, but here it is;
How about having duels give the options Maybe or No...
the maybe-- essentially so people can negotiate a 'wager' with one another, opening a window identical to trade window... (this way you could give odds like 10-1 or just say i'll give X amount if you win, or even items)... when both accept items are stored in neither's inventory & duel starts (this also saves watching system to see when duel starts)... Not sure what to do for logoff/crash etc... i would hope return to each respectively...
This would make for some interesting 'looting' in rp as an option... one could also put 'bounties' on their own head rping that the town guard is seeking you out for being evil or such...
Also I figure with the amount of dice gambling it would give a little more variety to what to bet on, not to mention what you could get for besting different opponents in combat...
I know i had other reasons, but off the top of my head am not recalling...
