Realism

[stern23]

It can't be that hard to realize. There's a server called Buxville that you can buy plots of land. People can even become landlords and buy multiple plots. On that land, they could build hotels and apartment buildings. There's tools they can use to define rooms within those buildings that they can rent out and the renter can only affect the defined area of that room.

Their caste system is cool too. They have three castes and you can choose one to join and advance through each one. The cool thing is, you advance by doing things for your caste. Merchants, for example, have to run certain number of auctions and make multiple business transactions. Once you complete these tasks, you talk to an NPC in the main city and pay a fee for him to "train" you to the next level in your caste.

I've never been on the server, so I don't know the specifics of how everything works. I was really interested in their system so I read through their forums a bit. Very cool stuff. I'm not saying that we should mimic everything they're doing, but we could use what suits us.
