A space world (especially a spaceship area <There I go again with the man-made construction!) would be very cool.
Banjo Kazooie or Tooie never actually did that before.
- I will not count N&B.
Though, Banjo Tooie had a 'fake' space area in WitchyWorld but wasn't a whole level or even real maybe. But I remember always walking into that machine area (The mini games) and felt like I was in a spaceship of my own I think and I think I also loved the planet one too.
