The TTC map seems the most different from its final version. Also, the note about the start pad for Furnace Fun is interesting- "Piccolo Podium disc from floor 3"? Thinking back to the third room of Grunty's Lair, there's nothing like that. Was what we know as the third room meant to be the fourth?
Wow, Cauldron Keep was planned to be a whole world? That's really cool. I'm really loving these insights into BK and BT. Thanks for posting them Nanirourou. I don't use Twitter, so I may have never found all this. Also, is anyone else having trouble reading some of these? I can't make out much text on the Castle World's page.
Really fascinating to see those old level designs from Banjo-Kazooie/Tooie. I'm also curious about what the supposed tenth world of Tooie called; "Weird Wild West" that Gregg Mayles mentioned on his Twitter account, would have been like if it didn't get cut out of the final version of the game.
