Why are Sonic's eyes green in Sonic Adventure, the franchise's first serious crack at a fully 3D polygonal platformer? It turns out there's a lovely little story behind that. Ristar creator Yuji Uekawa was the man tasked with revamping Sega's mascot for his debut on Dreamcast. Some of his decisions were practical: shrinking Sonic's enormous, swept-back skull and elongating his limbs, for instance, so that he doesn't look like a fuzzy joystick when viewed from the rear. Others were a touch more poetic. "He is always seeing these green pastures around him, like in Green Hill Zone," Uekawa explains in an interview conducted for Sega's 25th anniversary artbook. "I thought it would be nice to reflect that in his eyes."
With upcoming, downloadable, side-scrolling platformer Sonic 4, SEGA is taking the speedy blue hedgehog back to his Mega Drive roots. But what of Sonic Colours, the Wii and DS adventure game due out later this year? What roots, if any, is that game digging up?
Sonic Colours, then. It's another return to the hedgehog's roots, but in a different way to Sonic the Hedgehog 4's elaborate sprite tribute to his Mega Drive days.
