I really think something like this will displace some tourism/sightseeing (at least at the margins). I have done a ton of traveling all over the world and would much prefer a VR experience like this instead of cramming onto an airplane like cattle for hours, getting accused of being a drug lord at every border crossing, dealing with foreigners who seem to hate Americans, etc. Most tourist cities are pretty much the same anyway; a few jam packed attractions, the strip of overpriced fancy tourist trap restaurants, those gift shops you can buy cheap crap with the city's name on it, luxury hotels, adventure charter companies, etc.

Anyway, sorry for the rant but I liken this to going to a football game in the stadium vs. watching at home and I'd much prefer the latter.
