Nice to see some developer acknowledgement for one of their predecessors. I played UO for its first 5 years. Housing was interesting, and a far superior gold sink to anything in Warcraft. Hell, I even sold in-game housing for actual cash on a couple occasions. It's too bad Warcraft didn't implement some of the other parts of UO into WoW, as well. The profession/crafting system was top-notch. WoW's is garbage by comparison.The traditional player housing in MMOs isn't very interesting, maybe with the exception of Ultima Online. This was because you owned part of the world, making the area have real value.
