If you click on the “Macines” tab at the top of the page it shows you the number of locations that have each machine VS pinside members that own the machine.

It’s prettty interesting.
By that data I would say the home market is bigger than the market for games on location. Especially so for higher end models.

I suppose you have to take that data with a grain of salt as not all home use models are sold to pinside users.
Then again I would think that most locations get listed that are route games. I know I pretty regularly update locations when I’m out and about.
Either way I think with newer games it seems like more are going to the home market.
