Dating back to the days when Sega had their own consoles, the speedy blue hedgehog was seen as a rival to Nintendo's porky and short plumber, Mario. These days, there are no Sega consoles on the market and I now find myself reviewing the latest Sonic title on the Nintendo Wii – how times change.
For those of you that are not familiar with Sonic (where have you been?), the aim of most games is to run through levels as fast as possible, collecting rings and rescuing animals from his arch nemesis Doctor Robotinic, aka Doctor Eggman."
