[2021] In-Game gambling

I quite like this part of mmos. This can be a great distraction for crippling addicts such as myself me! .Maybe there could be a possibility that items could be betted on and there could be a gold estimation according to the average auction house price given so you can bet gold against it or bet an item of equal value, Or maybe... even deeds to player freeholds.
Taverns already have parlor games and these can be a nice addition to them.
