GameInformer did an interview about Sonic the Hedgehog 4 Episode 1 (2010). It features SEGA's VP Sales of Marketing, Alan Pritchard being silly as usual and also you can find Dan Ryckert talking Sonic with two of Retro’s most technically gifted members.
Pelikan: “Sonic 4 and SFR have very different art styles and many people have complained about SFR’s “busy” look, so comparing them is not simple.”
Mercury: “I think that SFR succeeds where Sonic 4 fails because it’s more surprising. There are so many details you’re not expecting to see, and that’s what makes it more exciting.”
