Couldn't make it to Summer of Sonic 2011? Fret not as we have a one hour retrospective for you to watch.

A few weeks ago the annual Summer of Sonic event was held and this year it was an extra special one to mark the speedy hedgehog's 20th anniversary. As usual the show was filled with games, merchandise and interviews and a one hour retrospective has been uploaded for you to watch in case you weren't present.
