Blue Spheres are back for a second time, FINALLY NOT THE HALF PIPE, but only a bonus for more content. Unlike previous games, you can have co-op with Tails or Knuckles and it is a blast (a better blast than 3D Blast). Tee Lopes is fantastic, Metallic Madness Zone Act 2 is like your in the popular night club. I failed to include in my CD review, that the developers knew what they were doing and have made fantastic fan games, along with Sonic 1, 2, and Knu- er, Mania. If you want that fast-paced, original platforming perfected, then this will make that 'want' yours. I love the great style of the originals that I played on Sonic Mega Collection.
Just kidding, this is a great, outstanding, AMAZING sequal to my favorite game, Sonic 3 & Knuckles.
