Sonic is almost at drinking age, the blue blur turns 20 this year and Sega will be putting out a new game this year, Sonic Generations, to celebrate his 20th anniversary. At E3 we got a little time with the hedgehog and now you can to. For a short period of time on Xbox Live or PSN you can get the demo for Sonic Generations. In this new segment called Demoed we take a look at game demos and let you know if they are worth your time or hard drive space to download. Check out the video down below.
