I think the best opening was Shadow Generations. The edgy hedgehog himself, appeared to be the coolest when his story opened up. It’s amazing what was accomplished in the making of Sonic x Shadow Generations which will always remain a memory in my mind. The return of non-revisited zones is so cool, bringing back Chaos Island, Sunset Heights, Space Colony Ark, and, of course, Kingdom Valley from the infamous Sonic the Hedgehog (2006).
