When Mario moved into 3D, it changed the industry, but the Galaxy era is where Nintendo stopped trying to mimic the real world and started playing with physics in a way that feels genuinely mind-bending.

This is widely considered the best 3D platformer ever made, and for good reason. It takes the "planets and gravity" concept from the first game and trims all the fat. It’s pure invention. One minute your kid is riding Yoshi, the next they’re using a "Cloud Flower" to create their own platforms in mid-air.

Why it wins the night: It’s a masterclass in introducing a mechanic, letting the player master it, and then tossing it away for something even cooler. The co-op mode is also a lifesaver for parents—a second player can use a Wii Remote to point at the screen, freeze enemies, and collect items, making it much easier for a younger kid to survive the tougher stretches.

The original is nearly 20 years old now, but you wouldn’t know it by looking at it. The "spherical gravity" means you can run all the way around a planet and jump off the bottom into the orbit of another. It builds incredible spatial reasoning skills because "up" and "down" are constantly shifting.

The conversation starter: Keep an ear out for the story of Rosalina. Unlike most Mario games, which have the plot depth of a wet paper towel, this one features a surprisingly touching backstory about her mother’s death. It’s handled through a storybook mechanic and is a great way to talk about grief and memory if your kid starts asking questions.

Before everything was 3D, Mario was about the perfect jump and the perfect suit. These two represent the absolute peak of the "side-scroller" genre.

Technically Super Mario World 2, this game looks like it was drawn with crayons and colored pencils. It’s gorgeous. You play as Yoshi carrying Baby Mario, and the "flutter jump" gives kids a bit more air-time and forgiveness than a standard Mario jump.

The friction point: When Yoshi gets hit, Baby Mario floats away in a bubble, screaming. That sound is specifically engineered to be stressful. For some kids, it’s a funny "hurry up!" moment; for others, it can trigger genuine anxiety. It’s a good moment to remind them that it’s just a game mechanic—the goal is to stay calm and get the baby back, not to panic.

If you want to show your kid why you loved games in the 80s, this is the one. It introduced the world map, the Tanooki suit (flight!), and the idea that a level could have secrets hidden behind the scenery. It’s fast, it’s smart, and the physics still feel better than 90% of modern clones.

The co-op catch: In the two-player mode, players take turns. However, they can also "battle" each other on the map to steal items or cards. If your kids have a "competitive" streak that usually ends in a meltdown, maybe steer them toward a more collaborative title or set some ground rules before the turn-stealing starts.

While not a "Mario" game by name, it’s the spiritual successor to the creativity found in the Galaxy series. You play as a character in a 2D storybook who discovers they can leap out of the book and explore the 3D world of a child’s bedroom.

Why it’s on this ballot: It’s the perfect "on-ramp" for kids who find traditional Mario games a bit too punishing. It has built-in "cheat codes" in the menu—like invincibility or one-hit kills—that let you focus on the story and the puzzles rather than the frustration of dying. It’s essentially a playable Pixar movie that rewards curiosity.

The biggest hurdle with Mario games isn't the content—it’s the difficulty curve.

Nintendo is famous for "easy to learn, hard to master." The first half of Super Mario Galaxy 2 is a breeze, but the "Special World" or the final Bowser fights can be genuinely tough. If you see the controller-grip tightening and the jaw-clenching starting, that’s your cue to hop in. Most of these games are better as a "hand-off" experience: let them do the exploring, and you handle the boss that’s been stomping them for twenty minutes.

Q: Which Mario game is best for a 5 or 6-year-old? The Plucky Squire is the gentlest entry point due to its accessibility settings, but Super Mario Bros 3 is also great because the controls are so simple. If you're playing together, Super Mario Galaxy 2 is the winner because of the "Co-Star" mode where you can help them from a second controller.

Q: Do I need an old console to play these? Not necessarily. While some were originally on the Wii or SNES, Nintendo frequently re-releases these on the Switch through their "Nintendo Switch Online" service or "3D All-Stars" collections. Check the Switch eShop first before hunting down an old Wii on eBay.

Q: Are Mario games "educational"? They aren't "math games," but they are masterclasses in iterative problem-solving. They teach kids to observe a pattern, try a solution, fail, and adjust their strategy. That "try, fail, adjust" loop is the core of scientific thinking, even if it's dressed up in a red hat and overalls.

You can't really go wrong with anything on this list, but if you want the most "magical" experience for a family night, start with the Galaxy series. It’s the one that will have everyone in the room leaning forward, wondering how the physics are going to change next.
