Sonic the Hedgehog 2006 was released for the PlayStation 3 and Xbox 360 as the first “next gen” Sonic title, but the final game was much different from the original tech demo that was shown a year before. In the game you would have been able to turn into Super Sonic at any given time, but it was left unfinished: it’s called the rainbow gem and it was found by a hacker named Link. Also some concept arts show “Venice”, an early version of Silver.

Beta intro with different camera angles of the boat (at the beginning), different music, different voice acting for Elise, and it skips the part where Elise sees Soleanna in flames
