Sega's first Sonic CD trailer showed just enough gameplay footage to get Sonic fans salivating. This new trailer is even better. First it plays up the game's roots as a Sega CD/Mega CD title; Sonic CD stands out as one of the best games on that quirky, beleaguered platform, in fact. The rest of the trailer focuses on the game's unique time-traveling aspects, complete with plenty of footage of Sonic in action.

Sonic CD was originally released in 1993. The new version (which is coming to Windows Phone, XBLA, PSN, iPhone, and Android) not only recreates the classic platforming game, it includes several enhancements. The display has been expanded to widescreen without stretching the image, making the game look better than ever. The original Japanese techno soundtrack will be included for the first time outside of the US. Gamers will be able to toggle between Sonic CD-style spin-dashing and physics or the Sonic 2 and 3-style. And of course, it will offer the Xbox Live Achievements we all crave.

Sonic CD is still scheduled to debut sometime in November or (more likely) December. Between now and then WPCentral will have a full interview with the game’s producer.

Xbox 360 gamers who crave a Sonic the Hedgehog fix sooner are in luck. The surprisingly awesome (yes, I mean it) Sonic Generations heads to retail on November 1. Generations features a mix of classic Sonic levels from the Sega Genesis era all the way to the present, all presented with 2D- or 3D-style gameplay. With Sonic CD and Generations, Sega is finally giving the fans what they want: quality Sonic titles with classic gameplay.
