I wouldn't mind if they went full on virtual reality like the old VR-1 at Sega World. After all, the technology has improved leaps and bounds since then and Dreamworld could have a one of a kind ride if it was executed properly.
The Australian theme makes me feel concerned, because I get the feeling Ardent will half-ass it and use little more than drone footage, cheap out on the simulator mechanism, and call it a day.
If they want to go the simulator route, it is imperative that Ardent take a look at what Disney and Universal are doing and see how they can replicate them within their budget. I'm looking at rides like Iron Man, Minion Mayhem, Simpsons, Star Tours, heck even the old BTTF ride Universal used to have. If Dreamworld's simulator is done very well, they could have a serious winner on their hands, and potentially even put them onto the world stage.
