-2 goals: entertain with trademark spee and more-refined gameplay in 2D and 3D; new actions for Sonic
-Wii stages share the same themes with PS360 version, but different designs to take advantage of the remote. Helped by Sonic Advance 2 and Sonic Rush teams
-Same actions in different versions (I guess that means tackled on waggle): buttons for basic actions, certain actions involve motion control
-Interactive combat sequences using motion sensing in remote and nunchuk
-Quick Step (evade obstacles without slowing), Sonic Boosts (hyperaccelerate/blow up objects)
– Action-Chaining: earn more energy by stringing together actions leading to special moves and shortcuts
– QTE for branching paths like PS360
– No passage of time during levels – day and night cycles are fixed to certain events/locations
– Originally envisioned as Sonic Adventure 3
– No multiplayer or online modes
