We've gone all-out to celebrate Sonic the Hedgehog's 20th anniversary this week, bringing you Staff Memories of Sonic the Hedgehog, a look at unreleased Sonic the Hedgehog games and Sonic's Nintendo games too.

With 20 years of rich history behind him, we want to know how Sonic's affected you, the gamers. What memories do you have of the blue hedgehog's gaming exploits? Do certain games hold special meaning for you? Did you discover him as a young tyke, or did Wii's Virtual Console introduce you to his 16-bit outings for the first time?

Leave us a comment below sharing your Sonic memories.
