Anthony on Idle Chatter says that player housing has worked well in LotRO and SWG, and wants to see it implemented into WoW. He brings up the instanced housing districts as an idea, an idea that makes a huge amount of sense, considering the instance portals are already set up. He proposes that there are two solutions to the housing issue, guild housing and player housing. In this scenario each would be an alternative spot to hearth to, and in the case of the guild housing, one would be able to read the Trade Channel within your dwelling.
As much as I love the idea of creating my own house for my characters, the one thing I noticed about the housing in EQII for instance that I did not like was the solitude. I much prefer the supergroup base concept from City of Heroes, where more than one person can enjoy it. In my mind, I would love to see guild housing with real world locations, so that much like Anarchy Online, the PvP element comes in and you can siege an opposing faction's guild lair. Wouldn't it add an additional element of risk to know that when you flag for PvP your guild hall is flagged as well? There is a lot that can be done beyond the traditional "this is where I keep my stuff, and those trophies no one will ever see" sort of housing concept. What good is a trophy if you can't show it off to passersby?
