Adding onto my house again this year, which will include a game room that will be somewhere in the region of 32' x 18' and will include regulation length tables for shuffleboard (22'), pool (9'), air hockey (8') and fussball. Darts as well, and thinking electronic is the way to go for the fun factor. Will probably include a regular dart board as well (one of the 2 Brent was looking at in his first post) for my own use but not for kids and drunk people.
Oh, and a urinal. No space for a bathroom in that room, but there will be one in the room immediately beneath it. So... might as well.
