Mario & Sonic at the London 2012 Olympic Games – Review (3DS Version)

Mario & Sonic at the London 2012 Olympic Games is one of my favorite games and our first Mario & Sonic crossover game! In the game you play Olympic Events based off the real life 2012 Olympic Games only with Sonic and Mario and their friends. In my review for the game, you’ll find out more!

Why Mario & Sonic at the London 2012 Olympic Games?

Mario & Sonic at the London 2012 Olympic Games on the Nintendo 3DS is a unique entry in the long-running crossover series featuring Mario and Sonic the Hedgehog. While the series is known for its party-style sports gameplay, the 3DS version takes a slightly different approach compared to its console counterpart, offering a more portable-focused and story-driven experience.

At its core, the game is a collection of Olympic-themed events, ranging from track and field to more specialized competitions like BMX and gymnastics. The 3DS version stands out by including over 50 events, which is actually more than the Wii version in terms of raw variety . These events are designed to take advantage of the 3DS hardware, incorporating touch controls, microphone input, and motion features. This gives the gameplay a fun, experimental feel, as each event tries to do something a little different.

One of the biggest highlights of the 3DS version is its Story Mode. Unlike many sports party games, this mode introduces a narrative where players must clear a mysterious fog threatening London before the Olympic Games begin . While the story itself is simple and lighthearted, it adds a sense of progression and purpose that helps tie all the events together. It also encourages players to try a wider variety of activities instead of just replaying their favorites.

Gameplay-wise, the experience is very much a mix of quick mini-games. Some events feel responsive and satisfying, especially those that rely on timing and rhythm. Others, however, can feel a bit awkward due to the reliance on different control methods like blowing into the microphone or rapidly tapping the touchscreen. This inconsistency is one of the game’s biggest drawbacks—it can feel “hit or miss” depending on the event .

Another notable feature is how characters are handled. The game includes a large roster divided into different categories, with each character having strengths suited for certain events . However, not all characters can participate in every event, which can feel limiting at times. While this adds a layer of strategy, it may frustrate players who simply want to use their favorite character in every competition.

Visually, the game is colorful and lively, making good use of the 3DS’s 3D effect. The environments are based on real London Olympic venues, but they’re stylized in a way that fits the Mario and Sonic universes. The music is energetic and fitting, though not especially memorable.

In terms of replay value, the game does a decent job. The large number of events, combined with multiplayer options, gives players plenty to do. However, because most events are short and somewhat simple, the experience can become repetitive over time—especially for older players.

Difference Between the 3DS Version and the Wii Version

The 3DS and Wii versions of Mario & Sonic at the London 2012 Olympic Games are actually quite different experiences. The Wii version focuses more on party-style gameplay, featuring modes like “London Party,” which plays like a board game with mini-games mixed in . It also includes “Dream Events,” which are imaginative, over-the-top versions of Olympic sports set in Mario and Sonic-themed environments.

In contrast, the 3DS version leans more toward single-player content and portability. It includes a dedicated Story Mode (which the Wii version lacks in the same form) and emphasizes quick, bite-sized gameplay sessions suited for handheld play. The control schemes also differ significantly—the Wii uses motion controls, while the 3DS relies on buttons, touch, and other handheld features.

Another key difference is structure. The Wii version allows players to freely choose events in a more traditional party format, while the 3DS version often organizes events through progression systems and character groupings. Overall, the Wii version feels more like a social party game, while the 3DS version feels more like a solo-friendly mini-game collection with added narrative elements.

How We Test Games

For testing games we use a Nintendo Switch firmware version 2H. Hardware includes Joy-con and Pro controller on a large screen TV. Tests are done with up to 5 players. We take turns playing and evaluating games.

Whenever possible we play multiple players. We also use a Nintendo 2DS, DS XL, and for PC games we use a Ryzen 7 1700x CPU, AMD RX580, running on Win 10. This game is up to 1-players on one Nintendo 2DS/3DS and 4-player with multiable devices.

Pros

• Huge variety of events (50+ activities)
• Fun and engaging Story Mode
• Great use of 3DS features (touch, mic, motion)
• Large roster of characters from both franchises
• Portable and easy to play in short sessions

Cons

• Gameplay quality varies between events
• Heavy reliance on luck or gimmicky controls in some mini-games
• Character restrictions can feel limiting
• Can become repetitive over time
• Less of a party-game feel compared to the Wii version

Summary

Overall, Mario & Sonic at the London 2012 Olympic Games is a solid, if slightly uneven, entry in the series. It shines most when you’re playing casually or enjoying the Story Mode, but it doesn’t quite reach the same level of excitement as its console counterpart. If you’re looking for a portable, content-rich sports game with plenty of variety, it’s definitely worth trying. However, if you prefer a more social, party-focused experience, the Wii version may be the better choice.
