Fuck what a complete turd! The only positive point I can think of is that its image quality, while having the same ugly brownish tints as all other Wii games have, is partially watchable.
It's not even really a full-fledged game, Sonic moves on his own and through the course of the various missions and levels you're merely required to tilt the remote with your wrist and press a bunch of buttons. It feels more like say, an extremely evolved version of Final Fantasy VII's (or many other RPGs') snowboard mini-game with Shenmue-like QTE events.
The worst is that it has excellent level design. While playing I was really amazed at how closer to the flow of 2D Sonics it looked like when compared to anything past 3D Sonic game. It sincerely seems like it would have played incredibly well with a traditional control scheme.
But this game's controls are laughably poor. The Wii's motion capture system sucks, and at times in the game it produces unbelievably awkward results. You'll frequently go through some very nagging issues when trying to jump beyond something, or to properly rebound on some enemies with a streak of properly-timed Wiimote wrist flexions.
I've only seen few locales, but feel absolutely no more motivation to invest any supplemental time into it. Not only that, but within an environment, you have various missions that use the exact same areas only with some gimmick objective to them, and only a few enemy/item swaps in the level itself. It's a cheap way to extend the product's life.
There is a story, some form of the "Thousand and one nights" fairytale adjusted to the Sonic universe, but it's complete garbage. Not only that but it's only a few frames displayed over awful voice acting. Seems like this game was rushed.
The soundtrack is one of the worst in videogame history too, I can't remember the last time I felt like turning a game off because the sound sucked. I literally felt like shouting "AHHHH SHUT UP!!! SHUT UP!!!" to this lame punk rock Sugar Ray-wannabe. Many Wiimotes are bound to be broken out of frustration by Wii gamers. A stroke of commercial genius from Nintendo.
I have a hard time to believe that anyone who claims to really enjoy this isn't a complete agenda-pushing nbot.
