Second life sucks...
NOW GIVE US REAL ESTATE IN WOW!!!!
It's be cool if guilds could own buildings.
I wasted so much time in my house in SWG. Private property is the biggest complaint I have in WoW. I guess there is no way to make in integrate well with the game, but I still miss that aspect of the genre.
It could be done. Make a building in the major cities like an "apartment block" or something, you could then have an instance door that takes you to your, or maybe your guild's, room. You could pay rent, or a stupid amount of money, for ownership. Decorate it or what not, doesn't matter, it'd just be cool.
It'd be something to buy after the epic flying mount.
