This is actually a good question that you asked. Made me start to think. We are in the process of selling out house, and we are going to custom build a house. I am planning on having one room in the basement that is going to be a game room or sorts. We will have a pool table, small air hockey table, one slot machine, 1 cocktail cabinet, a bartop cabinet, and probably 2-3 normal stand up cabs. If it wasn't for the pool table, I wouldn't need that much space, but that table adds another thing into the equation.
