I also find IGA saying he hates precision jumping a little disheartening. We're all used to it, we all know what an Igavania is so it's to be expected, but it would certainly be nice to see some more difficult jumps in this game. Ain't gonna happen, I guess.
I haven't followed up on Mighty No. 9 really, just waiting to see the final thing, but the difference between IGA and Inafune is that the former is a game designer whereas Inafune, to my understanding, is more of a producer. After all, he was an artist during the Mega Man series' greatest years, and I've never been too fond of the ones he produced. With IGA and Inti Creates at the helm, I expect a much more efficient and skilled development.
