Eh, I can understand waxing nostalgic about the Centorium, but there really wasn't anything special about MouseGear aside from the Dreamfinder vehicle bolted to the wall. Then again, I have a strong distaste for the weird obsession in 90's Imagineering with overlaying locations meant to be evocative of the future with tons of gears, raygun gothic details, and pseudo-steampunk machinery. Future World and Tomorrowland are supposed to be aspirational visions of the actual future, not a fantastical alterverse future that presents bygone technologies in more elaborate, fanciful fashion. While Creations Shop could stand to incorporate more whimsy, I think the aesthetic is definitely more on point.
