Nintendo Switch Online Leak Hints GameCube Classics Arriving Soon—See the Full List

Nintendo has quietly expanded the Nintendo Switch Online + Expansion Pack GameCube library again, and this month’s headliner is Treasure’s cult-classic platformer Wario World, now live in the “Nintendo GameCube – Nintendo Classics” app on Switch 2 systems at no extra charge for subscribers. The surprise shadow-drop follows December’s double-pack of Rayman 2 and Tonic Trouble for the N64 library and continues Nintendo’s cadence of monthly retro updates that keep long-time fans checking the NSO icon first thing on announcement day. Why Wario World matters • First 3D Wario platformer: launched in 2003, the game blends beat-’em-up grapples with treasure-grabbing platforming that still feels refreshingly weird two decades later. • Developed by Treasure: the studio behind Gunstar Heroes and Sin & Punishment gives the game a distinctively chaotic flair beloved by speedrunners and retro collectors. • Previously pricey: physical copies regularly topped $100 on resale sites; the NSO drop removes the paywall and adds modern perks like suspend points and rewind. How to play 1. Update the Nintendo GameCube – Nintendo Classics app from the eShop. 2. Ensure your account has an active Nintendo Switch Online + Expansion Pack membership. 3. Launch the app on Switch 2 (the service remains exclusive to the newer hardware) and select Wario World from the growing carousel of purple disc icons. Growing GameCube roadmap Since the GameCube catalog debuted in June 2025 with ten launch titles—including The Legend of Zelda: The Wind Waker and F-Zero GX—Nintendo has delivered at least one new game every month. December added Wario World ahead of the previously announced lineup, hinting Nintendo may continue to shuffle release order for maximum surprise. The company has already teased that Fire Emblem: Path of Radiance and Pokémon Colosseum are “coming soon,” two of the system’s most sought-after gems that routinely fetch triple-digit prices on the aftermarket. What’s next? Industry insiders point to Super Mario Sunshine and Super Smash Bros. Melee as likely 2026 additions, timed to fill gaps in Nintendo’s Switch 2 release calendar and to fuel competitive online play. Meanwhile, dataminers have spotted emulator strings referencing eternal fan favorites like Paper Mario: The Thousand-Year Door and Metroid Prime—suggesting Nintendo is preparing a first-party blitz to keep Expansion Pack renewals strong through the Switch 2’s sophomore year.

Bottom line With Wario World now spinning on modern screens, Nintendo is proving its commitment to deep-cut GameCube preservation while simultaneously bolstering the value of the Expansion Pack tier. If you’ve been waiting for a reason to upgrade—or to unbox that shiny Switch 2—Wario’s garlic-charged rampage might just tip the scales.
