I've had a Nintendo Switch for a while and do not know what new games to buy? I already own: Splatoon2, Mariokart 8 Deluxe, Super Smash bros. Ultimate, Minecraft, Mario Party, Just Dance 2018 and 2019, Pokemon Let's go Pikatchu and Mario Odyssey. It would be best if not so famous games that are good but would be proposed.
It's already "famous" but you just have to mention Zelda Breath of the wild.
I do not know what exactly you all count as famous, but I would already call these games famous and recommendable:
Mario Maker 2
New Super Mario Bros U Deluxe
Donkey Kong Tropical Freeze
Mario and Rabbids
A little less famous:
Octopus Traveler
Bayonetta 2
Xenoblade Chronicles 2
Hollow Knight
Celeste
Undertale
Yoshi's Crafted world
Come on:
Luigis Mansion 3
Links Awakening remake
Pokemon sword and shield
Animal Crossing New Horizons
Thank's for the Tipps
Fortnite
I already have my games that are not free
