Has there been a house based solely on a video game before or is it only when there's a tv show or movie that it's considered? Borderlands would've been awesome had the movie not been so bad, there's a lot of potential there.
It's rather old now but I wish they'd done a BioShock house (first 2 games) when they were still fresh. Rapture is a great setting that would've done well as a house.
