to hear rumors about it was for Star Wars: The Old Republic. Granted, this rumor stems from a BioWare employee at Gamescom being a little too tired and letting "housing" slip as one of the many features of the game. Of course, it's also just as likely that said person was so tired they simply misspoke.
Rumors have a way of digging into the brain, though, and this one is no different. If you think back to KOTOR and Mass Effect, both games had a kind of home base for the game's main characters. Wouldn't housing be pretty much the same thing? Yeah, we just went there.
