I want to say something at the top of this—I still think World of Warcraft: Midnight's player housing system is very, very good. That's not just to soften the blow of the microtransaction analysis I'm about to hammer Blizzard with, if player housing sucked I'd say that. But the bones are really solid. You've got enough creative control to create Star Destroyers, you can clip things to your heart's content, and there's a generous amount of decor already in the game.
However, with the expansion's release comes Hearthsteel, a new premium currency (hurk) that lets you buy store-exclusive decor elements. In practice this isn't that big of a deal, since if you don't have an item, chances are you can rotate and clip five different pieces into each other to achieve a similar effect.
