When this question is asked normally it's usually Metropolis or Sky Chase. So decided to up the Ante! Personally I think Emerald Hill, it's a first zone, but honestly the weakest first zone of the quadrilogy. It's by no mean a bad zone at all, but it's just everything else I enjoy more (Even Oil Ocean and Aquatic Ruin, which i'll defend to my grave)
