Video games, however, are one of the exceptions to this rule. They do buy video games. Lots of them. Maybe it's because they do not feel they are being ripped off by video games. A song, movie, or show always provides the same experience, but a video game can be experienced again and again and never be the same.
On an entirely different note, I feel that the future of attractions will be Dark Rides, some of which will make Spiderman look like a Ferris Wheel ride 15 years from now. When my future children say "Dad, Spiderman was cool back then?" and groan at me, that's when I'll know that the attractions have gone to the next generation.
Harry Potter's dark ride may be the litmus test. If Harry Potter doesn't surpass Spiderman (having been built a good 10 years later), it probably says a lot about how incredible and ahead of its' time Spidey was and still is.
Accessibility ought to be a must, too. Ideally, it would enable a more level "playing field" than people with various disabilities would encounter typically in everyday life.
In a nutshell : randomness is better than elitism at the Parks.
Your team building interactivity is a good idea -- but one I've also thought would be well worth developing much further (since the inception of Disneyland's Buzz ride as well as the late, lamented Virtual Magic Kingdom) is an exploration of ways for potential theme park guests to interact in real time with people who are currently on rides and attractions inside a given park.
I'd love to have an array of videogame "home versions" of attractions that interface (somehow) with their full scale, three dimensional in-park analogues (again: think Buzz Lightyear Astro Blasters as a template, albeit one that has barely scratched the surface of its potential).
How about an online gaming experience visit to The Haunted Mansion or Pirates or Spidey that ALSO somehow gives you preview peeks of people actually experiencing those attractions?
Promotional gold mine, there -- and I'm speaking as a guest who (in 2006) visited California instead of Florida for the perks of collecting a then-current set of Disneyland's VMK trading cards that interfaced with the online experience (I already had Walt Disney World cards, and that sealed the West Coast deal for me). AND I met up with a friend from Canada who did the same thing for the same reason.
Sure -- my friend & I are grownups, and we ribbed one another about being SO motivated by a videogame that it actually affected our real life behavior/vacation plans... but as much as we laughed it up it's still true.
More internet/in-park crossovers, please! :)
