- He knows some are serious, but he doesn't think characters like Ironman and Goku will happen. (p27)

- In Smash for days, there was restriction of a time span to offer updates and 3DS had a limited number of times to update. So Wii U version had to do the same. This is why Lucas, Roy, and Ryu released at the same time. (p33)

- If it's a one time purchase type of game, then it's more efficient for the company to start making the next game than keep updating. (p59)

- Updates are normal thing these days, but still they are voluntary service. (p59)

- He always thinks it's important to hear voices from people not speaking up. Real beginners don't speak up. (p61)

- He is not thinking of doing Smash ballot again. It was used in Smash Ultimate's development very much. (p63)

- Beyonetta was the first pick among realisable characters. Above her, there were old veterans like Snake and other characters that were already tried negotiating but got rejected. (p63)

- He was making the plans for Smash Ultimate during the vacation he got after Smash for DLC was done. (p69)

- He thinks games should not be created based on researched data alone and saying games only born to imitate other games are misfortune. Those data should be used for marketings or managements, not to plan new games. Old data are old. (p133)

- (Speaking of Super Nintendo World) 60 billion yen is enough to make every Smash game up to Ultimate and more with couple ten billion of changes. Not many Japanese games have budgets over 10 billion yen. (p139)

- He wish there were Smash Area in Super Nintendo World. (p139)

- Smash Ultimate's DLC wasn't a thing at the time around Famitsu column vol. 546 January 11th 2018, and it was planned without the developers will. (p165)

- They are not something sell that much so it's difficult to gather staffs. Sometimes better to move on to the next game. (p165)
