- working on another 3D Mario for the Wii reminded Miyamoto of the Ocarina of Time/Majora's Mask days
- Miyamoto says Majora's Mask was made in order to take advantage of the 3D framework of Ocarina of time
- Miyamoto says that when you make a new game, you can spend up to a full year just working on player movements
- Miyamoto felt it would have been a waste to not go back and use what the first Galaxy offered up
- the dev team went back to Galaxy and felt that the sphere-shaped design of game worlds wasn't fully utilized, so they used new tricks and gimmicks for Galaxy 2
- Galaxy 2 started off by using the same stage formations as Galaxy 1, but this was back when the game was internally known as Galaxy 1.5
- development of new ideas went so fast that Galaxy 1.5 quickly amassed 90% new content
- originally, the dev team thought they could make the game in a year's time, but it ended up taking two and a half years
- the full amount of time was spent on stage creation and fine tuning
- Hint TVs are once again explained as way to introduce Mario 2d fans to the 3d setting of Galaxy 2
- Miyamoto believes Galaxy 2 starts off 'at full acceleration'
- Miyamoto admits that the game is harder, and actually causes Miyamoto to slam tables and shout while playing
- the bonus DVD that shows control details and Super Guide videos was Iwata's idea
- Miyamoto is hoping players give the 'assist play' a try, as it's more fleshed out than in the original Galaxy
- Miyamoto worked on text editing for Galaxy 2, which was something he hadn't handled since Super Mario 64. This return was found to be enjoyable by Miyamoto, but it caused other staffers quite a lot of trouble.
