>>48304858I think he meant worst performing original paired versions. Third versions always have fewer sales despite being objectively better than the new games (in terms of gameplay at least, I know some people will argue that the story in BW and SM is better than the BW2 and USUM story).
Crystal sold 6.39 million units, while Gold and Silver sold 23.1 million
Emerald sold 6.32 million, while Ruby and Sapphire sold 16.22 million
Platinum sold 7.06 million, while Diamond and Pearl sold 17.67 million
Black and White 2 sold 7.63 million, while Black and White sold 15.64 million
Ultra Sun and Ultra Moon sold 8.77 million, while Sun and Moon sold 16.18 million.
But you're correct, the sales don't reflect the quality of the games. Otherwise LGPE and ORAS would be superior remakes to HGSS, which we know isn't true.
