These sells are much more impressive......they have so much more competition from other AAA games compared to Nintendo which typically is only good for indies and their own games
The most impressive part is without a doubt the fact that they have so many IPs that are selling these numbers. Whereas if you look at Nintendo it’s always the same Mario and Pokémon, barring the occasional lightning in a bottle Wii Sports type success. And of course Zelda has finally broken the 10 million barrier after over 3 decades. MS on the other hand deserves no mention as they have ever only been able to make one 10 million seller and that was over a decade ago when Halo 3 did it.
