We've been looking at new houses (here in California, not easy to find). It was kind of dismaying that even in 4,000 square foot houses, there is no assurance there will be an extra room large enough for a 9' pool table. We're now thinking of a custom.
This is exactly why I purchased my 30 year old house. Huge game room that I put my Gold Crown II and bar in. Also has a pool and Jacuzzi. Theres no way I would have gotten all this with a new or newer home in the Houston area.
