These locations become your PlayStation or game console. You need your own killer content like Zelda or something to get off the ground, but once you can offer development tools that offer access to such a large audience, the entrepreneurs will come and start building content for you.
You provide a set number of props like staircases, blocks, etc that can be arranged into a specific game rooms layout and then painted by the developers game giving you much more room than just a big open area to work with.
There are some really good POC’s out there, but it’s just a single location like a laser tag place servicing a single area. That’s not enough to build a critical mass of developers or players.
