Face it, Sonic has had some serious ups and downs. The originals from the Genesis (Mega Drive) days had us going GaGa over Sega. They were fun and extremely fast, two gameplay elements that have eroded over the years. Despite the glory, a number of spinoffs and additional characters crowded out the franchise and a sad serious of spinoffs ensued. Sonic R, Sonic the Fighters, etc. The series got a jump start in 1998 with new freshness that was known as Sonic Adventure. It properly brought the core of the series into the 3D era, and tapped into the heart of the game. Sonic Adventure 2 was no letdown either, delivering the same standard of gameplay.
Of course, we all know what happened from there. A crowded and highly competitive hardware market forced Sega to give the Dreamcast an untimely end. Ports of Sonic Adventure and other classic compilations helped them assume their new role as a third-party developer, but once again the quality began to slide. The Sonic franchise took the blow in stride too. Sonic Heroes, meh; Shadow the Hedgehog, WTF!?; Sonic the Hedgehog (2006), fail, Sonic and the Secret Rings, meh. Hidden gems like Sonic Rush became overlooked as fans lost faith in the series.
Another year, another game. Sonic Unleashed is slated for a 2008 release, and the debut trailer shown earlier in February failed to impress. Recently a new trailer with more gameplay footage has been circulating, and its changing a lot of opinions.
The gameplay switches from 2D to 3D, and the camera transitions are unobtrusive. It's still too early to pass judgement, so we'll have to wait for more news. For now I'll say things aren't looking worse the blue blur.
