Sonic Team
Sonic Team began working on "Sonic Unleashed" (2008) in 2005. It was conceived as a sequel to "Adventure 2", but became a standalone entry after Sonic Team introduced innovations to separate it from the "Adventure" games. With "Unleashed", Sonic Team sought to combine the best aspects of 2D and 3D "Sonic" games and address criticisms of previous 3D entries, although reviews were mixed.
