Sega look back at 20 years of their hedgehog mascot.

The speedy blue hedgehog known as Sonic turns 20 this year and Sega is celebrating it in a number of ways. As well as the upcoming Sonic Generations a new three minute retrospective of the series has been released. The video covers everything from the very first Sonic the Hedgehog all the way through to this year's Sonic Generations. We had a chance to play the latter recently so stay tuned to N-Europe for hands on impressions.
