GameZone has posted up a couple of video interviews they held at PAX this year, in which they interviewed SEGA’s Ken Balough about Sonic the Hedgehog 4: Episode 1 and another unidentified SEGA representative about Sonic Colours. Balough talks about how they incorporated fan feedback to Sonic 4, such as level tweaks to make the levels flow easier, reaching top speed quicker and a blurry effect on his quills to make it look like he’s “really hauling ass”.

In the Sonic Colours video, the SEGA rep explains how feedback has been incorporated into the game and also tells us in-depth, what the story is about, what Eggman is up to and how the Wisps are involved.
