Sonic the Hedgehog 2

Sonic the Hedgehog 2’s financial success was a major factor in Sega catching up to Nintendo in the early1990s console wars. It brought their market share up to 50% within six months of its release. Tails, whom Sonic the Hedgehog 2 introduced, would go on to become one of the most prominent and frequently recurring characters in the series, appearing and acting as Sonic’s sidekick in most of the franchise’s media.
