I want to talk about Sonic 1. Specifically, the term “Sonic 1”.
Following the release of Sonic the Hedgehog 2 in 1992, fans began to call the first game “Sonic 1”. The name is an easy way to differentiate the original 1991 game from Sonic the Hedgehog the comic series or the junior novel or OVA or 2006 game or 2020 movie or even the character himself. Fans have even given the Master System and Game Gear Sonic the Hedgehog the name “Sonic 8-bit” to make things less confusing.
