Aside from the jump from 2D to 3D?
Well 3D World is technically the immediate predecessor of Odyssey, and I'm sorry, but it's no contest, Odyssey crushes 3D World. There's certainly a time and place for 3D World and it's not a bad game, but to go from that to Odyssey, damn. Same with Triforce Heroes being the technical predecessor of Breath of the Wild. I don't actually hate Triforce Heroes, but it's at the bottom of the heap of Zelda games, while Breath of the Wild is near the top. Super Mario Party is another big jump from any recent predecessor, best since the Gamecube era at least, getting a series long since gone astray back on track.
I'd like to also nominate Portal 2 over Portal.
