Quoted from blondetall:We're out of money AND space, but we've measured (because we're stupid enough to do it) and the large walk-in closet attached to the theater (right behind the wall of Alien stuff) would indeed hold a widebody Alien pinball machine.
When you don't let lack of money or space get in the way of a new pinball machine, it's pretty much a sure sign you're going to get, so you might as well put the preorder in now.
