Sonic Adventure 2 - Unused Content & Trivia

EDIT: The voices at 12:57 (screaming) are unfiltered versions of the sounds that the biolizard makes. Yep! Those roars are really just Sonic and Shadow screaming with a bunch of effects added.

Sonic Adventure 2 has a lot of things that either go unused or have interesting connections to the game's development.
Here's a video I put together listing some of them! Credit goes to Windii for all the Japanese-related stuff.
