This is the story of Sonic Generations, but crossed over with the MLP:FiM universe, with Spike and the Main Six taking the place of Classic Sonic and Classic Tails with other MLP characters also appearing . Except for Green Hill, there will be different areas explored, as well as pony rivals and different era bosses. So while it will have its similarities to the console and 3DS versions of the actual game, it will definitely have its differences too.
