Most people buy machines for their families to have fun. 5 ball games make it more fun and interesting for families and friends. Especially the kiddies. PLUS, an added incentive for me is to make the game as fun and enjoyable for my wife, who has basically NO interest in pinball. If I want to add machines to my collection, I have to do everything I can to please my better half (AKA the Boss!) and make it so she's into it and having fun.
