I don't have my Switch by hand right now, but the vast majority of my games are NOT from Nintendo. In fact, only 3 (out of 50+) come to my mind right now: MK8DX, BotW and Game Builder Garage.
To be fair, most of my games are Indie titles, but it also contains bigger titles, like Mortal Kombat, Story of Seasons or Dragon Quest
