It's hard to say, because Disney never lets a good idea die - almost all of the attractions at DLRP are based (if only slightly) on those that have come before.
Here are most of the DLRP originals I can name:
Disneyland Park
- Main Street Arcades
- Legends of the Wild West (though perhaps similar to old DL attraction)
- Molly Brown
- Pocahontas Indian Village
- La Plage des Pirates
- Indiana Jones et le Temple du Peril
- Adventure Isle
- Le Passage Enchanté d'Aladdin
- Le Taniere du Dragon
- La Galerie de la Belle au Bois Dormant
- Alice's Curious Labyrinth
- Le Visionarium
- Les Mysteres du Nautilus
- Things like the Hyperion Airship at Videopolis...
Walt Disney Studios Park
- CinéMagique
- Animagique
- Moteurs... Action!
- Armageddon: les Effets Speciaux
- Crush's Coaster
- Cars Quatre Roues Rallye
- Walt Disney Television Studios (original)
- Disney Studio 1
Add more if I missed any. Walt Disney Studios is a very original park in terms of attractions, I'm very impressed! Most of them are top quality too.
