RPO will be a modest hit at best. With a 55-mil 4-day opening, I'm going to guess it'll probably sputter out around the 200 mil mark. Good business, but not enough where Uni will tap WB and Village Roadshow for the full theme park rights... besides I'm not even sure what an RPO ride would even be, or that people would even want one.
Feels like RPO would be better suited to a VOID-esque VR experience rather than an attraction. People want to explore the OASIS, not hop into a DeLorean and recreate the city race. I think people are just blinded by the nostalgic properties without thinking this through.
