3D World stomps so hard is not even funny. The only things Odyssey does better are graphics and overall ambition. But in every other aspect, 3D World is a lot better. Level design is better, soundtrack is TONS better, having 5 characters to play as + 4 player co-op > Cappy and everything that comes with him. And post-game levels in 3D World >>>> Post-game Odyssey.
