As Sonic the Hedgehog keeps running, the number of games in the series only increases, and fans may wonder which of them are worth playing.

When it comes to Sonic the Hedgehog, fans can't always agree on which game is the best. This is in part due to how Sonic has consistently been trying something new, which also gives the blue speedster a variety of different experiences across many titles. However, this also makes it hard to know which games are good for newcomers, as well as what titles are worth looking at as Sonic Frontiers seeks to change the series formula in November.

Even as Sonic the Hedgehog is no stranger to taking risks and trying something new on his adventures, some aspects of the series are shown better in different titles. While what exactly makes a "good" Sonic game is up for debate, some games are better experiences for the franchise as a whole than others.

The titles in this tier are the ones that the Sonic series has seemingly grown out of in recent years. These titles are listed here because they are either unavailable, or incredibly hard to track down, rather than strictly ranked for quality. Some have been left behind between console generations, while others have simply been lost to time.
