The original ground-breaking title makes its debut on the iPod! Rocket Sonic, the fastest blue hedgehog on earth, through hair-raising loop-de-loops and dizzying dives past pubbling lava, waterfalls and on as you gather up Rings and stop Dr.Eggman's schemes for world domination!
Sonic the Hedgehog was a popular platform game that first made its appearance for the Sega Genesis game system. LimeiBook86 has posted a Youtube video of the game in action.
