Look, people have been pretty divided on Mario & Luigi Paper Jam Bros since it hit the Nintendo 3DS back in late 2015. On one hand, you have the die-hard AlphaDream fans who missed the weird, lore-heavy original characters like Fawful. On the other, you’ve got the Paper Mario crowd who were still reeling from the shift away from RPG mechanics in Sticker Star.
It was a weird time for Mario RPGs.
Basically, Nintendo decided to mash two distinct universes together. It wasn't just a gimmick; it was an attempt to save two franchises that were starting to feel a bit repetitive. You had the 3D-ish world of the Mario & Luigi series suddenly invaded by paper-thin versions of the same characters. It’s a meta-narrative nightmare if you think about it too hard, but in practice, it’s one of the most mechanically polished games on the handheld.
I remember booting this up for the first time and thinking the humor felt... safe. But then the combat started. And honestly? The combat is where this game absolutely smokes its predecessors.
The Weird Mechanics of Three-Character Combat
The biggest change in Mario & Luigi Paper Jam Bros is the addition of Paper Mario as a third playable character. Usually, you’re just managing the A and B buttons for the brothers. Now, you’ve got Y thrown into the mix. It sounds simple. It’s not.
Paper Mario doesn't play like his fleshy counterparts. He can make copies of himself. This "Copy" mechanic acts as a multi-layered shield and a damage multiplier. If you’ve got six paper copies active, your Jump attack hits six times. But if a Goomba clips you, you lose a copy instead of HP. It creates this frantic, high-stakes rhythm where you’re trying to maintain your stack while timing Trio Attacks.

Trio Attacks are a massive step up from the standard Bros. Attacks. They turn the entire screen into a mini-game. One has you flattening enemies with a giant hammer while the three heroes play a sort of rhythmic squash. Another involves a kite. It’s chaotic. It’s loud. It’s incredibly satisfying when you land a "Great!" or "Excellent!" rating.
The complexity is the point. While the story might feel like a "Greatest Hits" of Mushroom Kingdom tropes (Peach gets kidnapped, Bowser teams up with Bowser), the actual moment-to-moment gameplay is arguably the most complex the Mario & Luigi series ever got before AlphaDream sadly went bankrupt.
Why the Paper Craft Battles Split the Fanbase
Let’s talk about the elephants in the room—or rather, the giant cardboard robots. Mario & Luigi Paper Jam Bros replaced the massive, screen-filling Giant Battles from Dream Team with Paper Craft Battles.
Instead of turning the 3DS sideways and rubbing the touchscreen until your wrist hurt, you’re suddenly playing a weird, rhythmic tank-control brawler. You’re on the back of a giant cardboard Mario, charging into cardboard Goombas and King Bob-ombs. To recharge your dash, you have to play a little rhythm mini-game on a platform.
Some people hated this. They felt it pulled them out of the RPG flow.

I actually think they’re kind of brilliant in a "so-bad-it's-good" way. They represent the core theme of the game: materiality. The game constantly reminds you that one world is made of atoms and the other is made of wood pulp. Seeing a giant cardboard Bowser built out of what looks like recycled Amazon boxes is a visual treat that the 3DS hardware handled surprisingly well.
The developers at AlphaDream worked closely with Intelligent Systems (the Paper Mario team) to make sure the "paper-ness" felt right. This wasn't just a skin. The way Paper Mario flutters through the air or slips through cracks in the wall changes how you explore the overworld. It’s a shame the environments themselves stayed mostly in the "Grass, Desert, Forest, Ice" rotation, because the mechanical potential for paper-based puzzles was huge.
The Battle Card System: Strategy or Bloat?
One thing people often forget about Mario & Luigi Paper Jam Bros is the Battle Card system. It replaced the Badge system from earlier games. You build a deck of cards that you can trigger during combat using Star Points earned by landing good hits.
- Some cards heal you.
- Some cards debuff enemies.
- Some cards literally just give you free experience points.
It added a layer of strategy that felt more like a modern CCG (Collectible Card Game). You could ignore it if you were a pro at dodging, but for the harder boss fights—and this game does get surprisingly difficult—the right card deck was the difference between a win and a Game Over screen. It was an experimental move. It showed that the developers weren't afraid to mess with the foundation, even if the "New Super Mario Bros." aesthetic made the game look more generic than it actually was.
The Tragedy of the Missing Original Characters
If you ask a fan why they prefer Superstar Saga or Bowser’s Inside Story over this one, they’ll tell you the same thing: the characters.
The Mario & Luigi series was famous for weirdos. We had characters like Prince Peasley, the Shroobs, and Midbus. In Mario & Luigi Paper Jam Bros, those unique NPCs are largely gone. They were replaced by Toads. So many Toads.
There’s a mission early on where you have to find dozens of "Paper Toads" hiding in the environment. It’s basically a massive hide-and-seek game that repeats several times throughout the campaign. While the "Paper Toad" missions are actually decent puzzles, the lack of visual variety in the NPCs makes the world feel less alive.
It’s the classic Nintendo "brand consistency" era. During the 3DS years, there was a clear push to keep Mario games looking like the "main" series. No weird designs. No new species. Just Mario, Luigi, Peach, and Bowser.
However, the dialogue still carries that AlphaDream spark. The interactions between the two Bowsers are genuinely funny. Bowser is arrogant and loud, while Paper Bowser is more calculated and equally arrogant. Watching them bicker over who gets to be the "real" King of Koopas is a highlight. The game is self-aware. It knows it’s a crossover. It knows it’s ridiculous.
Technical Performance and That 3DS Charm
Running at a crisp 60 frames per second (mostly), the game is a technical marvel for the 3DS. The animations are fluid. When Mario and Luigi run, they have that signature bouncy gait. When Paper Mario joins them, his 2D animations are synchronized perfectly with their 3D movements.
The music, composed by the legendary Yoko Shimomura, is as banger as ever. She’s the same person who did Kingdom Hearts and Street Fighter II, and you can hear that DNA in the boss themes. The music for the final encounter is particularly epic, blending the styles of both series into something that feels final and momentous.
But we have to be honest: this game marked the beginning of the end. AlphaDream filed for bankruptcy not long after the remakes that followed this game. Mario & Luigi Paper Jam Bros stands as the final "new" entry in a series that defined portable RPGs for over a decade.
Why You Should Still Play It in 2026
If you’ve got a 3DS or a 2DS gathering dust, this is a title worth revisiting. It’s not the best story in the series, but it is the best playing one. The "Easy Mode" and "Fast Forward" features for cutscenes show that the developers cared about player time—something a lot of modern RPGs still struggle with.
The crossover isn't just cosmetic. It's a deep dive into how two different ways of designing a character can coexist in a single battle system. It’s also a reminder of a time when Nintendo was willing to let their internal studios get a little bit weird with their biggest icons.
Expert Tips for Your Playthrough
If you’re diving in for the first time, or heading back for a replay, keep these things in mind:
- Prioritize Paper Mario’s Copies: In the early game, Paper Mario is your tank. Keep his copies maxed out. He can take hits that would KO the brothers instantly.
- Don't Sleep on Battle Cards: Buy the card packs in the shops. Even the cheap ones can turn a boss fight around if you get stuck in a loop of low health.
- Master the Trio Kite: It’s one of the hardest Trio Attacks to master, but it deals massive damage to all enemies. Practice it in the "Dojo" menu.
- Save Your Amiibos: If you have Mario-themed Amiibo, they unlock special "Character Cards" that are significantly more powerful than the standard deck.
Mario & Luigi Paper Jam Bros isn't perfect. It’s a bit too obsessed with Toads and the environments are predictable. But the combat is a masterclass in turn-based design. It’s a fast, funny, and mechanically dense RPG that deserves more credit than it got at launch.
Go find your stylus. Charge the battery. It’s time to save the Mushroom Kingdom... twice.
Actionable Next Steps
- Check your 3DS battery: These consoles are aging; make sure your battery isn't bulging before a long play session.
- Physical vs. Digital: Since the 3DS eShop is closed, you'll need to hunt down a physical cartridge. Prices are rising, so grab one soon if you're a collector.
- Update your firmware: Ensure your handheld is updated to the latest version to avoid any save data corruption issues known in older builds of the 3DS OS.
