| I'd suggest as an addendum to player housing have gambling in the game world.
Casinos perhaps where you could actually play with other players in game, with either games specific to your world, or real world betting games. Let players be able to host these games in their own in game homes as well, and gamble on the in game currency in whatever amounts they want to.
When you factor in the secondary market, you could take a pretty decent chunk of business from onlike betting sites if the games were fun and people actually enjoyed whatever form of gambling you wanted to institute. |
