I dont want to laugh at you. So i will tell you this. Switch was dominating UK for a while. Its game were featuring N1 in u charts. People are interested more in Switch exclusive than on Sony exclusive. Mario kart 8 sold 35.39m copies. April 2020 to march 2021, they sold 10.62M copies of mario kart deluxe. Compared to god of war, which sold 20m. A racing game sold more than god of war. this should show you that nintendo is a powerhouse thnx to its 1st party. Its why they are number 1 in the industry, interm of 1st party games.
Animal crossing new horizon sold 32.63m copies.
super smash bros ultimate sold 23.84m copies.
the legend of zelda breath of wild sold 22.28m copies.
Pokémon sword/ Pokémon shield sold 21.10m copies.
This is the result of their top selling 1st party games. Neither microsft, neither Sony can reach that number of sales. and they did that with 85.49m switch (as of may 6 2021). Sony sold 115.9m ps4 system (as of apr 28 2021), while Microsoft sold 49.63m xbox system (as of march 1 2021). This should help you understand, how big is Nintendo ips. and that is just the normal ips. There are other insane Ips that Nintendo havent made yet (Mother series, etc).
people dont buy it that much for 3rd party, because of its weakness. but still sells gangbuster. For your information, this system was released in march 3 2017, compared to ps4 which was released in November 15 2013, and xbox 1 being released in November 22 2013. The switch was late to the party for 3 years, and its sold that much systems, with not much 3rd party support like call of duty, or battlefield. That is how insane this system is.
