Centralized IP based lands yes. IP lands with multiple IPs unless they are based off culture like Far East, Africa, etc not so much and more likely come off like NFL while the theming is fine but its not like ohmergawd tear levels we see when people enter HP and to some extent Pandora.
Also a 60 acre park with Nintendo IPs would actually allow to some actual adventure interactive play for Mario, Pokémon, Zelda, Kirby and DK than a small 5-8 acre section where the ride takes up 2-5 acres leaving most to shops, walkways and backstage areas.
