Well, I guess we'll skip the incredible innovations from the Nintendo DS and Wii and go straight to the Switch:I own a switch.
Please explain this innovation you speak of
BOTW - open world Zelda, nothing I can say that hasn't been said on here 1,000 times. Completely reinvented the Zelda formula.
Mario Odyssey - Open world format, Cappy changed the focus to uses the various foes to explore levels with unique abilities.
Mario Maker 2 - Create your own Mario levels. First one was on the Wii U and thus flew under the radar.
Splatoon 2 - Completely unlike any first/third person shooter. First one was on Wii U and thus flew under the radar.
Pokemon Legends Arceus - Embraced open world game play, introduced new turn mechanics, allowed to catch Pokemon without battling
Nintendo Labo - No justification needed.
Astral Chain - Unique combat system and great puzzles. Brand new IP from Nintendo.
Cadence of Hyrule - Fighting to the beat of music
Beyond that, there are ton of Switch games developed by Nintendo that were great games even if they weren't incredibly innovative:
Mario Kart 8 Deluxe
Smash Ultimate
FE Three Houses
Luigi's Mansion 3
AC: New Horizons
Xenoblade Chronicles 3
Metroid Dread
Loz Link's Awakening
DKC Tropical Freeze (game's fukking hard)
Luigi's Mansion 3
Kirby Star Allies
Kirby & The Forgotten Land
Pikmin 3
Captain Toad.
Come on man..how are you going to say these are the same games over and over. Reserve that criticism for COD/Madden/2K.
