sonic was designed for 2D first, same with mario
2D allows for far more detail since you don't have to deal model complexity
as a result, when they translated the design to 3D, they needed to both compromise AND keep the design the way it looks
these models on the other hand, don't have that detailed 2D design to base their model off of
its the same shit with the newer pokemon games, the new pokemon are designed for 3D, not 2D
