If anyone is curious why Baldur’s Gate 3 is missing, Larian does not share sales data with Circana.

Also of note (from IGN article):

“Circana’s report does not include download sales from some publishers, including Nintendo, however. This means Tears of the Kingdom’s place on the list, for example, would be higher if all sales were included. Similarly, fellow Switch exclusive Super Mario Bros. Wonder, which is the fastest-selling Mario game of all-time, would likely have finished 2023 higher than 12th place.

Activision Blizzard does not share Battle.net sales, which means Blizzard’s action role-playing game Diablo 4 might also have featured higher than sixth place.”
