At an investment of $650k just for the simulator, and assuming you'd like to make that back in a year -- which is kind of a long cycle for video game content that gets stale quickly -- the operator would have to charge about $300/hr for access. This assumes they could sell 6 hours a day for 365 days, which is so overly optimistic it's laughable. At $600/hr, you might see the light at the end of the tunnel at a year, but who is going to pay that kind of rate outside of the DoD?

Are you kidding, at $650k, that's too expensive for arcade owners (do those still exist besides collectors?).
