My understanding was that there would not be rare items in MO, that that was a major selling point in its superiority over other games, though I could be mistaken.

At any rate, this is an interesting notion. The way I would like to see it implemented is perhaps including a large building resembling an arena, or an enclosed field within the city, or some (any) other area outside of it, in which people could reasonably hold a sparring match or small (or large) skirmish. Maybe in some cities, maybe in all, maybe even culturally-based. Then people could use it to fight (or not), could hold matches in it (or not), could take bets on those matches if they so desired (or join in, or dance, or auction off their goods, or whistle Dixie, etc).

My idea for auctions is somewhat similar, but I think "market" would be a better word. These would be structured like empty tracts of space in the town proper, or outside of it, or pretty much anywhere a few players decided to get together and make one. Then the players could advertise wares for sale, take money from other players for said items, and give the items to the respective buyers.
