The house you see in the photo above is Britannia Manor II, the home of Ultima designer Richard "Lord British" Garriott, and it's for sale. The medieval-themed home looks out over Austin, TX and features a 360 degree observatory with telescope, pool, grotto, waterfall, and most likely secret passages that lead to dungeons and/or gates to Hell. The asking price: $4,100,000.00.
Call me crazy, but most people with four mil sitting around to buy a house probably have their own unique visions for homespaces, and they probably don't include as many Dungeons and Dragons references as Garriott's, but still, I'd live there in a heartbeat... in fact, I'm thinking of getting 4,000 friends together together to pledge $1000 each and creating the ultimate nerd time-share! Who's in?
