The Green Hill Zone is the most well known zone from the Sonic series. It is also a popular fan site. The GHZ is probably most assosiated as Sonic's home, probably because it is where his adventure begins in the very first game. The GHZ was resurrected as the Neo Green Hill Zone in Sonic Advance 1. It also has been in many fan games, fan comics, fan fictions, and basically almost everything else fanmade.
