No way. I love DisneyQuest, I keep hyping it as the 5th Theme Park (I wish Disney would). Sounds like it's had some decline in food options and maintenance (like the parks). But it's still amazing. Yea, maybe not quite $50-without-a-discount amazing, but it's something you can't get anywhere.
Off the top of my head, I can think of the really-neat to mind-blowing experiences there:
I guess what I'm saying is at-home entertainment can in no way compete with DisneyQuest's unique experience.
I think you're greatly overvaluing the appeal/importance of the gimmicky control and feedback systems in place in the various DisneyQuest games.
The point is that at their core, all of the Disneyquest games, besides having hopelessly outdated graphics, are extremely simple and short.
This is very much by design, since DisneyQuest was conceived as a diversion to entertain a guest for a couple hours at most, and guests would be expected to wait in line for several minutes before each interactive activity, which would probably only be "ridden" once or twice, much like in a theme park.
Moreover, the games have to be accessible enough that everyone from a 5-year-old kid to his mother, neither of whom plays video games, can learn them and have fun right away.
Problem is, that's 1998's model.
Today's 9-year-olds spend 4 hours a night on Call of Duty and build scale replicas of the Taj Mahal in Minecraft. Disneyquest's overgrown Smartphone app games with gimmicky canoe paddle controllers have nothing to offer them.
Today, DisneyQuest is so poorly-attended that the games could be ridden repeatedly, but why would anyone want to? The only Disney-Quest exclusive game that offers any kind of depth is the Alien Encounter: Invasion game, which has potential and plays like an alpha build of some sort of MechWarrior clone crossed with Battlefield 1942's driver/gunner/gunner setups.
They were marginally impressive for their time, but for the average visiting kid, who likely has experience with something like Nintendo's Wii, or an Xbox Kinect, or even a Guitar Hero controller, everything at DisneyQuest is going to look VERY old hat.
At least they still have AfterBurner Climax and Let's Go Jungle.
