How Sonic the Hedgehog was conceived to help Sega compete against Nintendo in the early 90s was discussed during a postmortem for the original game at this year's Game Developer Conference.
Sega has unveiled Sonic Mania Plus, an updated, expanded version of last year's excellent retro-inspired Sonic Mania. It's due out this summer on Switch, PS4, Xbox One, and PC.
Sonic Mania Plus was revealed during Sega's snappily titled Gotta Go Fast: The Official Sonic the Hedgehog Panel at SXSW Gaming, along with a full run-down of its brand-new features.
First up, Sonic Mania Plus will introduce two classic series stars as playable characters: Mighty the Armadillo and Ray the Flying Squirrel. Both debuted in the 1993 isometric arcade spin-off, SegaSonic the Hedgehog, and most recently had a cameos in Sonic Generations.
Sega's upcoming Sonic the Hedgehog movie now has a release date: 15th November 2019.
It's a year later than expected - a vague "2018" date was whispered when the Paramount project originally got greenlit, back in February 2016.
But work on the film is now underway, Hollywood Reporter writes. There's a director and writer (no one you'll have heard of), while Deadpool director Tim Miller is executive producing.
Sonic Mania contains a lovely tribute to a Sonic hacker who died tragically in 2013.
UPDATE 31st August 2017: Sega has said the offline play bug that affected the PC version of Sonic Mania has been patched.
Sega has also added a Denuvo warning to Sonic Mania's Steam page.
In a post on Facebook, Sega said it found a problem within the game code that prevented people playing offline, and denied it had anything to do with the game's controversial DRM.
Sonic Mania is chock full of references to the blue blur's 25-year legacy, with no shortage of fan service for the most dedicated of Sega connoisseurs. Yet there's one Easter egg that's so subtle and self-deprecating that only the most ardent of aficionados will catch it. Thankfully, we have one such man on staff with the Digital Foundry's eerily perceptive John Linneman putting his Sonic knowledge to the test.
Sonic Mania's PC release has been pushed back from 15th August to 29th August, Sega announced in a livestream today.
Sonic Mania will have a competitive mode in which two players race each other through stages in horizontal splitscreen.
Developer Sega has revealed Sonic Mania's bonus stages and time attack mode in new gameplay footage.
Sonic Mania is now slated for a 15th August launch on Switch, PS4, Xbox One and PC.
Digital pre-orders are 10 per cent off on Steam, bringing the price to £13.49 / $17.99. On consoles it's the regular price of £14.99 / $19.99.
The pixelated retro sidescroller was originally planned for a spring release, but it was delayed for the developer to put on the finishing touches.
UPDATE: Sega's released a gameplay video of Sonic Forces, the 3D Sonic game due out later this year on PlayStation 4, Xbox One, Nintendo Switch and PC.
Sonic superfans The Great Lange and Murasaki Fox have whipped up a prototype for a fan-made game called Sonic Utopia and it's got a heck of a trailer.
After initially saying the Sonic Mania Collector's Edition wouldn't come out in Europe, Sega has now announced it will, in fact, come out in Europe.
First, the good news: Sega just announced a brilliant Sonic Mania Collector's Edition.
Sega has announced two new Sonic games - one that's a retro remake of sorts and one that's completely new.
The new game is dubbed Project Sonic and is due next autumn. It's in development for NX, PC, PS4 and Xbox One. A cinematic trailer announced it and heavily suggested there will be co-op. Sonic is joined by another Sonic while he runs towards a giant Robotnik, presumably, and the video's tagline reads: "When things look their darkest, even heroes need a helping hand."
The adjoining press release doesn't add anything further - only that the game is being made by Sonic Team, which, well, what on earth else would it make?
