I give it a 6. The classic sonic sections were loving perfect. Only issues is the music? The composer is stuff for classic sonic stages. Modern sonic was made worse, why? No loving clue, Colors and Generations proved that the gameplay can be great if LEVEL DESIGN and MOVEMENTS are tweaked. Seriously, modern sonic is like 95% on rails, then when you do have to control him, he moves like a loving autistic child. I'm not gonna even go into the custom character stages, Im mortified. I can't wait to randomly pick up this game again in the future and basically play ONLY the classic sonic sections and pretend in my forgeted up head that there is no other way to play the game, only classic sonic.
