So to sum up, attractions based on Tron, a movie about computers in 1982 fits Tomorrowland's theme, but aliens and interdemensional travel does not?
I just want to make sure I'm clear on the theming hypocrisy here.
Answer in the form of a question:
Where's the people scanner so I can upload my body in Second Life or the Game Grid? Or AI on the level of the MCP or Tron himself?
It's decades-away futuristic technology created by a plot device uber-genius that can't possibly exist right now save for the work Flynn and company.
Lightcycle battle, whether simulator or well-done dark-ride, TL or DQ, would be great. I'd especially like a head-to-head multilayer lightcycle simulator. Anyone ever tried playing network lightcycles? Because of the timing involved, it can't be done properly on the internet because of lag, let alone even a decent home network. It'll work for a while, but you get a network buffer overload and BAM, right in the light trail. Such a simple concept, a simple game whose rules anyone can learn in seconds, and yet all our powerful day-to-day computing can't handle it.
If they could scan you into the game grid via an effect similar to the transporter in the Las Vegas Star Trek: The Experience, it'd be a great bit of continuity too. I wouldn't mind some disc-battles either. I could see this with off-the-shelf body position technology in use with webcams, or a device like a Wii remote. The Alien Encounter game at DQ could serve as a platform for game grid tanks too.
Heck, even a ride in a Recognizer a la Body Wars, looking down on the game grid, helping squash the bad guys and rooting for your bike could be something.
