Nintendo's latest entry in the Pokemon series has smashed the Switch's sales records, becoming the fastest-selling Switch title in the console's history.
The Let's Go titles are semi-remakes of Pokemon Yellow and feature elements from the Pokemon Go mobile game.
For reference, The Legend of Zelda: Breath of the Wild sold 1.3 million units in its first month, while Super Mario Odyssey boasted two million copies sold in three days.
It should of course be noted that Pokemon's sales have been helped by an install base of more than 22 million consoles, a milestone the Switch passed in October.
Our review of Pokemon: Let's Go, Pikachu! scored 8/10 and celebrated the game's "stunning graphical style and approach which wonderfully blends players desire for 3D Pokémon games with the core tenets of the franchise."
