To hype the launch of the SNES Classic Edition, Nintendo has been posting interviews with developers of the games that appear on it. Sure, they’re on a marketing page for the unit, but in the spirit of the great Iwata Asks roundtable discussions, they’re chock full of details on how and why the games were made.

For example, we get the real story on why Star Fox 2 was canceled. Dylan Cuthbert of Argonaut Software previously speculated that it had to do with the imminent launch of the Nintendo 64. He is partly correct. Shigeru Miyamoto said launching Star Fox 2 on the Super Nintendo would have required another chip, the Super FX 2 (successor to the Super FX developed for the first Star Fox) and that would have raised the price of the game.
