I'm curious, does the "no clones" mandate only apply to rides? Or does it also apply to restaurants, shows and lands?
EDIT: Just for clarity, I've typed out some of the rides that are exclusive to Non-UOR parks as well as canceled concepts that could feasibly come back.
Non UOR Experiences
Super Silly Fun Land, SLOP, Sing on Tour, Freeze Ray Sliders
Jurassic World, Jurassic World Adventure, Canopy Flyers
Puss in Boots Giant Journey, Far Far Away, Kung Fu Panda Land and Boat Ride, Dreamworks Theater
Transformers Metrobase, Battlestar Galactica (don't think there would be much interest in cloning these outside of China)
Waterworld, Special Effects Show, Lights Camera Action with Steven Spielberg and Zhang Yimou, Space Fantasy, Jaws
Canceled Attractions
2013 Kong New York concept
Lorax trackless ride
SLOP Trackless Ride
Spongebob Boat Ride
"Iron Man" Flying Coaster (Death eaters? Was this system even feasible?)
"Puzzle Theater"
Potter VR
Attractions with Easy "Clones"
Bourne -> Bond
F&F Hollywood -> London
Any generic unthemed outdoor coaster
EDIT 2: Also apparently Mama Mia is one of the highest grossing movies in Britain, so there's your stage show I guess.
