Sonic the Hedgehog was a classic game that Sega created back in the day. Back then it was considered cutting edge graphics. I remember thinking it was so cool. Well most of us don't have Sega anymore and so our best option is to find a version of sonic online. This program installs a link directly on your desktop to give you convenient access to a flash version of sonic the hedgehog. This version is different from the original and not created by Sega.
