machine. I would say the ping pong table was used most by our teens/friends. Air hockey gets used hardly at all. Foosball and pinball somewhere in between. I like pool so I got that for me. It doesn't get played a ton; but enough that I think it's worth having. I love the pinball machine; but the upkeep costs are high. I probably wouldn't buy that again unless I could find one that I was confident wouldn't need many repairs.
