According to Jim Hill's latest podcast (just uploaded) (and I'm paraphrasing here) the Millenium Falcon ride will seat six per cockpit, with seven in operation at all times with a 3.5 minute ride time. He says they wanted initially to have real interaction- your actions directly impact what happens. Each person would have a job, and if you don't do your job, the Falcon crashes and the ride is over. Which is causing problems. In the initial version, If you know what you're doing, the re ridability of the original version was insane. But they've been doing play testing in Glendale, and what they're finding is that it can be more frustrating then entertaining. If you're paired with people who don't get it, and cause problems, it can lower the ride enjoyability. With an "on the ball team" the ride is amazing, but for the other 90%, it can have problems. At one point, there was talk of a dedicated Galaxy's Edge website where you could watch the tutorial and be prepped before you come to the park.
I'd be curious to learn more about how recent his information is- since this is an obvious issue that can be encountered in a team based simulator, especially with strangers in the cockpit. Wouldn't they have developed a solution long before they approved and built the ride? Obviously, a true simulator that allows for flight and combat- with virtually unlimited freedom for the players that can have new worlds programmed in sounds AMAZING. A next level Star Tours. But if they have to significantly limit the freedom of the pilots in order to make it a feasible ride concept, then that's also a problem since it can have a "I can't take the training wheels off" feel which can be equally frustrating.
If his information is as recent as he made it sound, and accurate, then it further solidifies my beliefs that this generation of Imagineering is inept and lacks the both the creative vision and beautiful execution we've seen with previous generations of Imagineering. TP2000's posts a little bit ago about the Marvel Land issues line up with these latest Jim Hill rumors.
