Did you share your Nintendo Switch user data with Nintendo ? If so you can now view your Year in Review.
Year in Review
Your Year in Review shows you what your most played games have been on your Nintendo Switch system and how many hours you have spent playing. The Year in Review site only seems to work if you have shared your play data with Nintendo. If you have turned that off then you won’t be able to see your Year in Review.
You can still activate it now to be able to view such data next year.

Personally I had it disabled, so I cant share the experience it offers.
