Guys, I can't stress how important it is you read the book. It's very clear that how the game turned out was because SEGA of America's involvement. They saw the concept, asked for it to be changed to omit what was weird/crazy about it to appeal to all audiences. They axed Sonic's girlfriend with the"great cleavage", and changed some aspects of his design, as in Japan he was very serious looking, though in the game I always felt that remained. Sonic's band members would have stayed as part of the soundtest regardless of their ommission from the gameplay itself, but due to time constraints that was axed and what came of it was the SEGA logo screen you see today, which is infinitely famous. Notice that Sonic was meant to have his jumping celebration pose, and it even mentions how long this would have lasted. If the game had not been changed we might not all be here today as Sonic may not have been that popular if SoA hadn't stepped in. Also, it is pretty clear Ancient didn't just do their own thing, and had some set earlier ideas about what Sonic was before they were left to their devices. They may even have had some of these concepts to use as reference, as there's some great similarities. Glad now that I bought a copy of the SMS game as it's important to the history of the game we all know and love.
