19. Sonic the Hedgehog 2 (SMS)

Sonic 2 (8-bit) is definitely worth a look for Sonic fans who perhaps missed out on the Master System/Game Gear entries. It is sufficiently different from the first 8-bit game to warrant investigation, and it's got more of the series' excellent music — we're particularly partial to some Sky High Zone, but it's all good. It's not a patch on Genesis Sonic 2, but direct comparison is a little unfair given the hardware. Overall, this Sonic 2 has its own identity and it's a fine 8-bit take on the hedgehog's trademark platforming.

18. Sonic Generations (3DS)

Sonic Generations has a lot going for it: it looks good and offers plenty of content, and when it's on form it succeeds in combining satisfying platforming and the 'hog's trademark speed in a single package. Some design choices miss the mark though, and it's undeniably short and unambitious compared to something like Super Mario 3D Land. It never quite recaptures the original games' vibrant spirit that made them stand out all those years ago, but this is a fair attempt.

17. Sonic the Hedgehog (SMS)

This is one of the best examples of a platformer on the Master System and easily the match of Alex Kidd in Miracle World. Going 'backwards' to this might be jarring If you started with Sonic on the Mega Drive, but taken on its own merits Sonic the Hedgehog on the Master System (and Game Gear) was a fair approximation of the slicker 16-bit game with bespoke levels and some great audio to boot.

16. Sonic Superstars (Switch)

We had a few issues with Sonic Superstars — the local co-op could have greatly benefited from split-screen support, and the online Battle Mode feels incredibly shallow and tacked on — but this is the first original 2D Sonic game that feels truly authentic to the Genesis titles without aping the classic pixel-art style, and for a lot of longtime fans, that's frankly an absolute miracle. Zipping through the 12 zones in the excellent campaign made us feel like kids again, but it will also prove a great entry point for new players looking to see what all the fuss is about. Developer Arzest's reputation has taken a beating in recent years, but this is a triumphant effort from the studio and a great return for '2D' Sonic.

15. Sonic Rush Adventure (DS)

Sonic Rush Adventure brought back Blaze the Cat from the previous game and gives you the option to play as the feline or Sonic himself (obviously). While still a side-on 2D platformer, this game incorporated 3D sections and expanded on the traditional Sonic gameplay with adventure game elements that fit the template rather well as Sonic and Tails did their best to leave Blaze's island and get back home.

14. Sonic Advance 3 (GBA)

Another solid 2D entry in the Advance series that proved there were still good 2D Sonic games being made in the 2000s if you looked on handheld systems. Sonic Advance 3 starred all your favourite characters, plus Cream the Rabbit, and provided a fitting final part to a trilogy of winning platformers on the Game Boy Advance.

13. Sonic Colours (DS)

Whilst the majority of the gameplay will feel familiar to Sonic veterans, particularly those who enjoyed his previous DS outings, the Wisps genuinely refresh Sonic Colours' gameplay by adding new routes to spice up each stage. It’s fast, loud, bright, and bold, and a recommended slice of high-speed action that offers something different from its bigger brother on Wii (and Switch in Ultimate form).

12. Sonic Origins (Switch eShop)

Sonic Origins is, on one hand, a near-definitive way to experience four stone-cold classics that represent some of the highest peaks of Sonic's career. On the other, most of these games are already readily available and there aren’t many new features or additions to justify buying them yet again. The cutscenes, museum elements, and missions are all very pleasant but they're also the minimum you would expect for a series this prestigious and popular, and the disappointing Plus DLC/Version adds in playable Amy and a dozen Game Gear titles.

For players ready to play these classics for the first time, Sonic Origins is the go-to way to experience Sonic’s 16-bit heyday. Die-hard 2D Sonic veterans may be less enamoured with the package and the small but noticeable differences between the Classic Modes presented here and the games in their true original configurations. Regardless, it's sure nice to have Sonic CD available in a convenient form on the most convenient of consoles. Not perfect, then, but great comfort-food gaming.

11. Sonic Advance 2 (GBA)

Building on the good foundation put down in the previous entry, this middle game in the Sonic Advance trilogy upped the difficulty to a level that put some players off, but Sonic Advance 2 retained the elements that made the first game such a good translation of the 2D Sonic formula to the GBA platform: great music, lovely visuals, clever level design, and — above all — that proper Sonic 'feel'. You haven't got to go fast, but it's highly encouraged.

10. Sonic Adventure DX: Director's Cut (GCN)

Seeing the DX version of this on GameCube was, for many, extremely odd at the time as we couldn't imagine seeing SEGA's mascot on a Nintendo home console. The Dreamcast original wowed anybody old enough to remember seeing Sonic in proper 3D for the first time, so having it on GameCube was something special, and not a little strange.

Time hasn't been as kind to Sonic Adventure as some games from the era, but there's something about the promise of its opening stage which gives it a special place in our affections.

9. Sonic Advance (GBA)

In the decades since the shocking first appearance of Sega's mascot on a Nintendo handheld, it's fair to say that not every team that's worked on a 2D Sonic game has nailed the delicate sense of inertia and tight physics that characterise the classic 16-bit titles. Sonic Advance is one such example that just gets it. Developer Dimps retains the classic feel and course design that made the originals special while adding fresh elements that prevent it from feeling like a re-tread of old ideas. Vibrant visuals, charming animation, excellent audio; add multiplayer into the mix — as well as the Tiny Chao Garden that linked to the Gamecube — and Sonic Advance is a platforming treat up there with hedgehog's finest.
