Sonic the Hedgehog turns 35 in 2026, and the celebration is in full swing with the anniversary collections, new racing content, the works.
So everyone is jumping on the trend and dusting off the classics: Sonic 2, Sonic 3 and Knuckles, Sonic Mania. But you already know those. You have probably beaten those. This is not a list about those.
Sega has spent 35 years scattering genuinely great Sonic games onto consoles and handhelds that most people never owned. A Sega CD gem here, a Neo Geo Pocket surprise there, the best handheld Sonic ever made sitting quietly on the Nintendo DS.
These are the ones that got buried by bad timing, weird hardware, or a single loud flaw that scared people off. Here are seven overlooked Sonic games worth tracking down, roughly in the order Sega released them.
| ▶ The short version: if you only know Sonic from the movies and the famous Genesis trilogy, Sonic CD and Sonic the Hedgehog Pocket Adventure, are the ones that will surprise you most. If you want the best pure Sonic you have not played, jump to Sonic Rush. |
Platform: Sega CD, now on modern PC and consoles
Why you missed it: It was locked behind the Sega CD, an expensive add on almost nobody bought
Sonic CD is regularly called one of the best games in the series, and it is also one of the least played, because owning it in 1993 meant owning the Sega CD. That is a shame, because it is basically three games in one.
Every stage exists in a past, a present, and a future, and by racing to signposts and time travelling you can literally change a level's future from a polluted wasteland into a bright utopia. Add the debut of Amy Rose and rival Metal Sonic, plus one of the most beloved soundtracks in Sonic history, and you have a classic that most fans have only read about.
Platform: Neo Geo Pocket Color
Why you missed it: It was made by SNK for a handheld that barely reached the West
Here is the deepest cut on the list, and one of my personal favorites. In 1999, SNK built a Sonic game for its own Neo Geo Pocket Color, and against all odds it is superb.
Pocket Adventure borrows the bones of Sonic 2, then remixes the stage layouts and folds in ideas from across the Genesis era, all running with the crisp speed and sharp pixel art people thought a tiny handheld could not manage.
It picked up real critical acclaim at the time and then vanished with its host console. If you love the idea of Sonic on unexpected hardware, this is the holy grail. We get into that little machine more in our piece on whether a Neo Geo is worth it in 2026.
Platform: Game Boy Advance
Why you missed it: It arrived quietly as Sonic made his first jump onto Nintendo hardware
Sonic Advance is a small piece of history: one of the first Sonic games on a Nintendo system, right after Sega left the console business.
Developer Dimps, who would go on to shape 2D Sonic for years, delivered a fast, faithful, gorgeous return to Sonic's roots at a time when the series was drifting toward 3D experiments. Four playable characters, tight classic level design, and a pace that feels exactly right on a handheld. It is one of the best portable platformers of its era, and it is easy to forget it even exists.
Platform: Nintendo DS
Why you missed it: People stopped expecting good Sonic right when the best handheld Sonic showed up
If you play one game off this list, make it Sonic Rush. Widely considered the best handheld Sonic ever made, it uses the DS's two screens to send you rocketing up and down enormous vertical stages, with a boost driven Tension Gauge that makes momentum feel electric.
It introduced Blaze the Cat, packs a fantastic Hideki Naganuma soundtrack, and nails the one thing Sonic games so often miss: speed that feels earned rather than out of control. It arrived during a rough patch for the brand's reputation, which is exactly why so many people skipped a game that deserved a pedestal.
Platform: Xbox 360, PS3, Wii, PS2
Why you missed it: One divisive idea, the Werehog, sank the whole game's reputation
Sonic Unleashed is the classic case of a great game hiding behind a bad headline. Everyone remembers the nighttime Werehog stages, the slow brawler sections nobody asked for. Almost nobody gives credit to the daytime stages, which are stunning, blisteringly fast, and effectively invented the Boost formula that modern Sonic has run on ever since.
Play it for the daylight and you will find some of the best pure speed the series has ever produced, wrapped in genuinely beautiful visuals. The Werehog is the price of admission, and the daytime levels are worth it.
Platform: Wii, later remastered as Sonic Colours Ultimate
Why you missed it: It was a Wii exclusive at first, easy to overlook next to the big HD consoles
Sonic Colours is the game that quietly started Sonic's redemption arc. It is bright, funny, tightly designed, and built around Wisps, little alien power ups that reshape how you move through a level.
Because it launched on the Wii rather than the more fashionable HD consoles, plenty of players never touched it, and it took the later Ultimate remaster to get it in front of a wider audience. If your mental image of late 2000s Sonic is nothing but disappointment, Colours is the one that proves otherwise.
Platform: PC, PlayStation, Xbox, Switch
Why you missed it: You did not, if you are a fan, but a lot of casual players never gave it a shot
This one is a curveball, because Sonic Mania is not obscure, it is adored. But it lands here for a specific reader: if you only know Sonic from the movies or a vague childhood memory of the Genesis, you may never have played what is arguably the best classic style Sonic ever made.
Built by fans turned developers, Mania is a love letter to the 2D games, remixing beloved zones and adding brilliant new ones with animation and music that outshine the originals. If any modern game is going to make you understand why people love this hedgehog, it is this one.
For sheer surprise, chase down Sonic CD and Pocket Adventure, the two most people have literally never touched. For the best game you can start playing tonight, it is Sonic Rush or Sonic Mania.
And if you want to see the exact moment modern Sonic found its footing, it is the daytime half of Sonic Unleashed and the whole of Sonic Colours. Thirty five years in, the famous games are only half the story. The other half is hiding on the hardware you skipped.
What is the most underrated Sonic game?
Sonic CD and Sonic the Hedgehog Pocket Adventure are the strongest picks. Both are genuinely excellent and both were trapped on hardware most people never owned, the Sega CD and the Neo Geo Pocket Color.
What is the best handheld Sonic game?
Sonic Rush on the Nintendo DS is widely considered the best handheld Sonic ever made, thanks to its dual screen vertical stages and boost driven momentum.
Is Sonic Unleashed actually good?
The daytime stages are some of the best high speed levels in the series and invented the Boost formula modern Sonic still uses. The nighttime Werehog sections are the divisive part, but the daylight half is well worth playing.
Where can I play these old Sonic games today?
Many are available through modern collections, reissues, and digital stores on PC, PlayStation, Xbox, and Switch. The deepest cuts like Pocket Adventure are best experienced on original hardware or through collections when available.
Why is Sonic trending in 2026?
2026 is the 35th anniversary of the Sonic the Hedgehog series, which has brought anniversary collections, new racing content, and a wave of renewed interest in the back catalogue.
Fantasy Online 2 is a gorgeous 2D pixel MMORPG, rebuilt by the creator of a game the internet lost in 2014. The zones and music are lovely and the questing respects your time, but the combat has no impact and nothing in the world will ever try to kill you.
Hakkyu no Kiseki is the high school dynasty mode hiding in Pro Spirit 2026, and it might be the best thing in the game. Here is how the three year player cycle, weekly practice, and single elimination tournaments work, plus how to survive the roster gap that wrecks most first runs.
