Why does Modern Sonic have 2D sections? Isn't that the thing of Classic Sonic? Or do both have 2D and 3D sections? I think it would be better if Modern Sonic only handled the 3D sections, because giving 2D sections to him just makes Classic Sonic kind of pointless from a gameplay perspective.
I agree 100% here. Classic should be 2D only (which he is), modern should stay 3D, then maybe mix it up with the OC stages (which appear to be mostly 3D).
