Agreed.
Nintendo is miking Mario, Zelda and Pokemon like crazy, which is devaluating these franchises mid-term, instead of diversifying.
- Super Mario Odyssey, Super Mario 3D World Deluxe, New Super Mario U, Super Mario Party, Mario Kart 8 Deluxe, Mario Kart Ar, Mario Kart Tour, Super Mario Run, Mario Tennis Ace, Super Mario 3D All-Stars, Super Mario Maker, Mario Paper: Origami, Captain Toad Treasure Tracker, Mario+Rabbids: Battle...
- Zelda: Breath of the Wild, Zelda Hyrule Warriors HD, Zelda Age of Calamity, Zelda Wind Waker HD, Zelda: Link's Awakening, Zelda: Breath of the Dark, Zelda: Cadence of Hyrule
- Pokemon Let's Go Pikachu & Eevee, Pokemon Sword & Shield, Pokemon Snap, Pokemon Quest, Pokemon Café Mix, Pokemon Unite, Pokemon Go, Pokemon Shuffle Blitz, Pokemon Masters, Pokemon Whatever the fuck etc...
And where are F-Zero? Starfox? Waverace? Metroid? Donkey Kong? New stuffs? Old stuffs?
They're initial success relied on AAAA games (big exclusive AAA games), two actually BoTW and Odyssey, some AAAs like Mario Kart, Super Smash, Pokemon 8 or Luigi's Mansion3...and an incidentally successful AA game, Animal Crossing. But what else?
