Donkey Kong Country Returns on the Wii/3DS had 8 worlds, plus some hidden stages. The 3DS version had an entirely new 9th world that the Wii version didn’t have.
Even though Tropical Freeze needs three more months in the oven, getting delayed until February last week, it appears to have less worlds than Donkey Kong Country Returns.
Nintendo revealed this detail by saying:
Journey across six different themed islands with unique areas like Mangrove swamps, Savannah storms, ocean depths, and the frozen landscape of DK Island.
Seems like a detraction if you ask me. I’m got use to DKC Returns having 8 whole worlds to play through. Now, if Retro ups the level count in these six worlds it may not matter at all that it has two less worlds than the previous game.
