No way man. PHOF survives because it is cheap, has lots of variety, owns the land it sits upon, and runs on a tireless human engine with deep knowledge of antiquated technology.
If you ditch the EM's, jack up the prices, and move it to the strip it would be bankrupt within a week. Faster still without my coin, because the vast majority of what I play are EM's.
Pinball as a form of entertainment, alone, cannot financially sustain itself outside of an inexpensive, tax-advantaged venue with passionate, knowledgeable techs. Upkeep is expensive and among the most demanding of any form of amusement on the planet. Have a look at the pinball arcade at New York, New York. That's the only sustainable model outside of the "museum" approach/private collection: Fewer games, higher prices, bigger crowds, and bolstered by alcohol and food sales.
My 2c? Break up PHOF into a few dozen high-quality barcades across the country. Each with passionate, knowledgeable owners and varying themes. Track scores across all locations, sell food and drinks, get tournament players involved, dress up the environment, charge more, and unify under a national brand. You'll get better information sharing and management methods, more people involved, and maintain a higher overall quality of games. It would also build national public exposure for pinball as a competitive sport (and provide locals an opportunity to participate)... leading to an eventual niche ESPN-treatment like PAPA/Pinburgh. Not to mention growing the hobby overall.
I imagine 1000+ games would require at least 30 locations each with investors/owners/techs with a good slice of what makes Tim tick... while remaining open to change and a willingness to serve the demands of a modern audience. I'm already on track to accomplish this with my own barcade project, but as part of a national competitive sport network and unifying theme? That would be on a whole different level.
Not likely to happen due to the business logistics involved, but if it happened, passionate people like us would be the ones to carry it forward. Anyway... just thinking out loud...
