It's been exactly 25 years since Sonic the Hedgehog's loop-the-loops and pinball speed revolutionised our gaming lives.
Before the little blue cannonball burst onto the scene in 1991, the Mega Drive was struggling to lure us from the charms of the Nintendo NES and a certain moustachioed plumber.
But that all changed thanks to an incident on the technicolour South Island. With his eye on the island's six Chaos Emeralds, Dr. Robotnik started imprisoning local animals and (naturally) turning them into robots. Sonic came spinning from a hedgerow into the Green Hill Zone, and the rest is gaming history.
Sonic the Hedgehog's searing speed, eye-popping colour and catchy tunes were so good that we barely touched the copy of Altered Beast that came bundled with our Mega Drive.
And it was the perfect gateway drug to dozens of trailblazing classics that suddenly made Mario look drab and monochrome. Here are the brilliant Mega Drive games we turned to after finishing off Dr. Robotnik in Final Zone...
25) Columns (1990)
Nintendo had Tetris, and the Mega Drive had Columns. It didn’t start off life on the console, having been originally developed for the Atari ST, but Sega snapped up the rights when it saw just how damn popular Tetris was with Nintendo gamers.
Take some classic match-3 gem stacking, add repetitive-yet-strangely-compelling music, and throw in an ancient roman theme for good measure, and Columns was the result. Guaranteed to eat up hours of your life in huge chunks.
Sure, the Mega CD version sounded better, and Tetris was so addictive it’s got an honest-to-goodness medical condition named after it, but if you wanted a puzzle fix in the 90s and weren’t a Nintendo fanboy, this was your go-to game.
24) Altered Beast (1990)
A beloved arcade port involved a buff dude punching and kicking beasts and the undead, while consuming enough steroidal power-ups to transform into a variety of werebeasts.
Set in Ancient Greece, it evokes old school stop-motion epics such as Clash of the Titans and Jason and the Argonauts. Interestingly enough, it was the original pack-in game of the Mega Drive in many countries before a rebranding exercise changed it to Sonic the Hedgehog.
23) The Revenge of Shinobi (1990)
Also known as Super Shinobi, this series was probably the main reason why the gaming world was so obsessed with ninjas in the ‘90s.
It was a terrific side-scrolling, hack-and-slash (and shuriken) action game in which you play a ninja (duh) on a quest for vengeance (duh).
One of the hardest games on the Mega Drive, the game was also infamous for featuring several iconic level bosses or rip-offs of iconic characters. Revenge of the Shinobi was soon followed by several well-received sequels and became one of Sega’s most famous franchises.
22) Fantastic Dizzy (1991)
Your girlfriend’s been kidnapped, your best bro is frozen in ice, monsters are crawling all over your treetop village, and you’re a giant anthropomorphic egg. Welcome to Fantastic Dizzy.
This explore-em-up had no combat - it just feautred a massive side-scrolling map and plenty of head-scratching puzzles that left you cursing your tiny three-item inventory capacity every time you forgot where you’d left that one crucial key. The soundtrack was phenomenal too, and pumped out atmosphere from the Mega Drive’s Yamaha YM2612 audio chip.
21) Outrun (1991)
The best thing about Outrun - apart from the Ferrari, winding open roads, epic skids and huge vistas - was the music. Not only did they completely nail the authentic* handling and feel of driving a Ferrari Testarossa Spider, the soundtrack was the perfect accompaniment to your checkpoint-filled coast-to-desert race.
'Passing breeze', 'Splash wave' and 'Magical sound shower' were all mega chiptune hits that would still sound radical if you were cruising the West Coast in your drop-top 458 Italia today.
*Having never driven a Testarossa, we can't actually vouch for the authentic handling.
