What is interesting about the game is the Luna Market? It is active as any market in real life. Why? Mechants. My suggestion is to create non-home based merchants in the towns around the banks. Consider bull dozing the Inn at britian (or is it a tavern) and making a modern market. Tented with tables under it. Or something like that. Players can apply for vendors. The costs become a gold sink. 1 vendor per account. Make the selection random, make them monster slaying rewards whatever. Build it so players dont own the homes in brit, just rent the vendor spot. Wipe out a few building around brit and create a market. The Brit Bizzare, Mondains Market or whatever. You get the idea. As long as you supply enought vendor tables, it should be cool.
