The Switch has a ton of local co-op games or just 2 player multiplayer.
What I think is lacking are games with 4 player support, my friends and I haven’t found too many games that support 4 players, at the top of my head there are:
Mario Kart 8
Puyo Puyo Tetris
Super Bomberman R
So while its true there’s a lot of 2 player games, I think there are very few with 4 player support, which is great for parties.
