While both titles share the same name in North America, they’re different games with different stages. So far, the only common stage is Green Hill from the original Sonic the Hedgehog. Casino Night from Sonic the Hedgehog 2, Mushroom Hill from Sonic & Knuckles, and Radical Highway from Sonic Adventure 2 are in "Blue Adventure." That’s what the 3DS title is called in Japan – Sonic Generations: Blue Adventure.
