The PHOF is a great place to visit and play. Machines are being worked on constantly so most aren't down for long when they are. However, if you visit one time for a hour or two, that may happen to be the time some of your favorites are out of order. That's just the nature of pinball.
Tim is a good guy but clearly can't spend all day everyday chatting up everyone. The target customers for PHOF are adults looking to play games they remember from decades ago and current pin enthusiasts more than young kids swinging from the plunger of a woodrail.
