GP blogger Evil Jester writes, "As you all know, June 23rd 2011 was the 20th birthday of Sonic the Hedgehog. Garnering rings and busting Dr. Robotnik became a large part of gaming life in the 1990’s and for those of us who grew up in that time Sonics’ existence is the core of many happy memories. I myself turn 20 this year and to this day I still find time to pop on my old Sonic games and relive the glory days of platforming. To celebrate this momentous occasion I have compiled a list of my favourite levels from the original Mega Drive titles: Sonic the Hedgehog, Sonic the Hedgehog 2, Sonic the Hedgehog 3 and Sonic & Knuckles. Hope you like it."
