Game Boy Advance Hidden Gems Worth Hunting Down
We called the Game Boy Advance the single best system to collect for in our console collecting guide, and the argument rested on its library. But that library has the same problem the SNES has: a first tier so famous — Pokémon, Mario, Metroid, Zelda — that it buries a second tier full of strange, brilliant games nobody bought. The GBA's second tier might be the best of any handheld ever made. It launched into the shadow of the PS2 era, so dozens of superb 2D games arrived to a market whose attention was elsewhere. Their loss. Here's our shortlist, same rules as our SNES gems piece: if it's on this list, there's a real chance you never played it.
Astro Boy: Omega Factor (2004)
Treasure — the studio behind Gunstar Heroes and Ikaruga — took a licensed anime tie-in job and, apparently out of sheer inability to do otherwise, delivered one of the best action games on any handheld. Omega Factor is a beat-em-up-shooter hybrid with screen-filling bosses, a surprisingly serious story that weaves together decades of Osamu Tezuka's universe, and a structural twist midway that recontextualizes the whole game. Licensed games are supposed to be shovelware. This one's a masterpiece with Astro Boy on the box.
Ninja Five-O (2003)
A ninja cop with a grappling hook, in a game that plays like Shinobi and Bionic Commando had a child raised by an arcade. Konami released it with essentially zero marketing, it sold nothing, and cartridges became some of the most expensive on the system — collectors know what the market didn't. The grappling swing is perfect, the level design is dense with hostage-rescue routing, and the whole thing radiates early-2000s confidence. It finally got a modern re-release, which took mercy on wallets.
Drill Dozer (2006)
Game Freak, in between Pokémon obligations, made a platformer about a girl in a drilling mech — and put a rumble motor inside the cartridge itself. Drilling through gear-work levels feels fantastic; the drill is movement, weapon and puzzle key at once, with a gear-shift system that rewards timing. It arrived at the very end of the GBA's life when everyone had moved to the DS, which is the only reason it isn't a household name.
Boktai: The Sun Is in Your Hand (2003)
Hideo Kojima's handheld experiment: a vampire-hunting action game whose cartridge contains a real solar sensor, so your in-game weapon literally charges from sunlight. Playing it meant going outside — design as lifestyle intervention, twenty years before anyone said "touch grass." The stealth-action underneath is genuine Kojima craft, and the whole package remains one of the boldest physical-hardware gimmicks ever shipped. Emulators simulate the sensor nowadays, which is convenient and slightly heretical.
Kuru Kuru Kururin (2001)
A launch-window game about guiding a slowly rotating stick through narrow mazes. That's it. That's the game. It's also one of the purest precision-under-pressure designs Nintendo ever published — the same white-knuckle, one-more-try loop that powers Celeste's hardest screens, decades early and in pastel colors. Europe and Japan got it; North America inexplicably didn't for over a decade.
Rhythm Tengoku (2006)
The first Rhythm Heaven game, Japan-only, and still arguably the best. Fifty-odd microgames about rhythm alone: no lanes, no notes scrolling at you, just you internalizing a beat and delivering it. It was the GBA's last first-party release in Japan, shipped after the DS had already conquered the world, and it plays like a studio making exactly what it wanted with nothing to lose. Import cartridges are affordable and the game needs zero Japanese to enjoy.
Mother 3 (2006)
The least "hidden" game here — its absence from Western release is one of gaming's most famous grievances — but statistically, most players still haven't actually played it. EarthBound's sequel is a funnier, sadder, more formally daring RPG than almost anything in the genre before or since, with a rhythm-based combo system and an ending that earns its reputation. The community's English fan translation is legendarily polished; our emulation legality explainer covers how patch-only distribution keeps that work on the right side of community norms.
Car Battler Joe (2002)
Vehicular combat plus RPG plus garage-building sim, from the studio that made Medabots. You assemble battle cars from parts, take missions across an open desert, and fight real-time arena duels that feel like a 16-bit Twisted Metal with character progression. Deeply weird, deeply charming, and the kind of mid-budget experiment that simply doesn't get made anymore.
How to actually play these
The GBA makes this easier than most retro platforms. A modded original unit with a backlit screen (covered in our collecting guide) plays everything beautifully, and flash cartridges are the community standard for running your own dumps and fan translations on real hardware. Cartridge prices split wildly: Car Battler Joe and Kuru Kuru Kururin stay reasonable, while Ninja Five-O and Drill Dozer originals cost serious money — check for modern re-releases first. However you get there, the GBA's second tier rewards the trip: it's the sound of 2D game design at full maturity, playing to an audience that had already left the room.
