This shows, among other things, how many hours you have spent with the Nintendo Switch this year (buy now 399.00 €) have spent. The day with the longest playing time and a total of the days that were active on the switch can also be found in it. One or the other number should certainly surprise you in this review. Here are some examples of the statistics that you can find there:
the most used games of 2020 the genres played in 2020 the number of gold points earned in 2020 the day with the longest season of 2020 the total number of Hours of Play in 2020 In the USA there is a section on the official Nintendo website where you have to log in to see your personal Switch year in review. Such a section does not (yet) exist in Germany. Maybe Nintendo will follow suit in this regard in this country. However, there is another possibility: If you have registered with Nintendo with your e-mail address, you will receive an e-mail with the relevant statistics. If you haven't received it yet, you can do so in the next few days - until the end of the year.
