It was the playground argument that defined the nineties. You were either a Nintendo kid or a Sega kid. There was no middle ground, no dual-citizenship, and certainly no world where the blue hedgehog and the Italian plumber shared a cartridge. If you told a kid in 1992 that there would eventually be a massive library of sonic games with mario, they would have laughed you out of the cafeteria. Honestly, back then, it felt like a betrayal of physics.
Fast forward to today. The rivalry is a relic.
Now, we have over fifteen years of history where these two icons compete, cooperate, and occasionally punch each other in the face. But how did we get here? It wasn't just a business deal. It was a seismic shift in the gaming industry that happened when Sega officially exited the hardware business in 2001. When the Dreamcast died, the barrier fell. Suddenly, the impossible became the inevitable.
The Olympic Catalyst: Where It All Started
In 2007, the unthinkable happened. Sega and Nintendo announced Mario & Sonic at the Olympic Games for the Wii. People lost their minds. It wasn't a platformer, which felt like a missed opportunity to some, but it was the first time they were officially in the same box.

The game was a massive commercial hit. It sold over 10 million copies. Why? Because the novelty was irresistible. You could finally see who was faster in a 100m dash. Spoiler: the game balanced their stats so Mario could actually keep up, which is technically nonsense if you follow the lore, but great for gameplay balance. This series became the bedrock for sonic games with mario. We’ve seen iterations for Beijing, London, Sochi, Rio, and Tokyo.
Each entry in the Olympic series tries to do something different. For instance, the 2014 Sochi Winter Games version utilized the Wii U GamePad in ways that were... let's say "experimental." Some people loved the touch-screen curling; others found it clunky. That’s the thing about these crossovers—they often prioritize "party game" fun over the tight, precision platforming both series are known for individually.
Breaking Down the Smash Effect
If the Olympics were the "friendly" introduction, Super Smash Bros. Brawl was the real meat. When Sonic was revealed as a late-addition guest character for the 2008 Wii hit, the internet basically broke. This wasn't just sports; this was combat.
Sonic's inclusion in Smash changed the meta of the game entirely. His speed was unparalleled. He was annoying to fight. He was fast, twitchy, and his "You're too slow!" taunt became legendary. Since Brawl, Sonic has been a staple in Smash 4 and Smash Ultimate. In Ultimate, the roster grew so large that we didn't just have Sonic and Mario; we had Shadow (as an Assist Trophy), Knuckles, and Tails appearing alongside Peach, Luigi, and Bowser. It’s the ultimate digital toy box.
Why We Never Got a Core Platformer Together
You might be wondering why, after twenty years, we still haven't seen a "Mario & Sonic Adventure" style 2D or 3D platformer. It's a valid question. Most sonic games with mario are either sports titles or fighting games.
The reality is complicated.

Design philosophy is the main culprit here. Mario games are built around "momentum-based precision." You jump, you land, you hit a specific spot. Sonic is built around "flow and speed maintenance." Combining those two styles into one cohesive level is a nightmare for developers. If you make a level fast enough for Sonic, Mario feels like he’s moving through molasses. If you make it technical enough for Mario, Sonic hits a wall every three seconds.
Shigeru Miyamoto and Yuji Naka (the original creators) have both spoken in various interviews over the decades about the mutual respect between the teams, but the mechanical friction is real. Instead of a shared platformer, Sega and Nintendo found a "safe" middle ground in the Olympic license. It allows them to use the characters without having to solve the impossible physics problem of their respective worlds.
The Fan Game Underground
Because the official companies haven't given us a "real" platformer crossover, fans took it upon themselves. If you go looking for sonic games with mario online, you'll find a massive "fangame" scene.
- Super Mario Bros. Crossover by Jay Pavlina is probably the most famous example. It’s a browser-based game where you can play the original Super Mario Bros. levels as Sonic, Mega Man, or Link.
- Playing as Sonic in World 1-1 is a trip. You realize very quickly that the levels weren't built for his speed. You fly over obstacles and end up in pits you never knew existed.
- There are also ROM hacks like Somari, which is a bizarre, unofficial port of Sonic 1 to the NES featuring Mario. It’s terrible. It’s glitchy. But it’s a fascinating look at how badly people wanted this crossover to happen before it was legal.
The Cultural Impact of the Team-Up
The collaboration between these two brands saved Sega's mascots from fading into obscurity. By putting Sonic on Nintendo hardware, Sega reached a whole new generation of kids who never owned a Genesis or a Saturn. It turned a bitter rivalry into a lucrative partnership.

Interestingly, the "vibe" of these crossovers is always very sanitized. You won't see Mario and Sonic having a deep, cinematic heart-to-heart about their past battles. The games are bright, loud, and family-friendly. They represent the "Disney-fication" of gaming's biggest icons. While some older fans miss the edge of the 90s "Sega does what Nintendon't" marketing, the reality is that the partnership has been incredibly stable.
How to Experience These Crossovers Today
If you’re looking to dive into the world of sonic games with mario, you have a few distinct paths depending on what kind of gamer you are.
- The Competitive Route: Super Smash Bros. Ultimate on the Switch. It is the gold standard. The interactions are brief, but the gameplay is top-tier.
- The Party Route: Mario & Sonic at the Olympic Games Tokyo 2020. It features some great 2D "retro" events that use the 8-bit Mario and 16-bit Sonic sprites. It’s a nice nod to the history.
- The Retro Route: Digging up a Wii or a Wii U to play the older Olympic titles. Some of the "Dream Events"—which are fantastical versions of sports set in places like Green Hill Zone or Peach’s Castle—are actually the closest we’ve ever gotten to a shared platformer.
The most important thing to remember is that these games are built for fun, not for deep lore. They are a celebration of the fact that the "Console Wars" ended and everyone survived. Well, except for the Dreamcast. Rest in peace.
To get the most out of these crossovers, don't just stick to the modern titles. Look for the "Dream Events" in the older Wii-era Olympic games; they often feature unique remixes of classic music that blend the two worlds better than any of the standard sports minigames. Also, keep an eye on the Smash Bros. Spirit Board. There are dozens of minor characters from both franchises represented there, providing a much deeper "crossover" feel than the surface-level roster suggests.
If you really want to see the "what if" scenarios, check out the speedrunning community for Super Smash Bros. Ultimate. Watching a high-level Sonic player take on a Mario specialist is the closest you'll ever get to seeing that 1990s playground debate settled in real-time. It’s fast, it’s chaotic, and it’s exactly what we dreamed of thirty years ago.
Next Steps for Players:
- Check the eShop: Nintendo often discounts the Olympic Games titles during real-world Olympic cycles or holiday sales.
- Explore Smash Spirits: Use the "Vault" menu in Smash Ultimate to read the descriptions of Sonic characters; it’s a great way to see how Nintendo interprets Sega’s history.
- Try the 2D Mode: In the Tokyo 2020 game, specifically seek out the 10-meter platform dive or the marathon. The 8-bit/16-bit hybrid aesthetic is easily the best part of the modern crossover era.
