Man, American comics are such a damn oddity considering how much cultural impact the characters have...
On a regular month, Batman will sell less than 125 000 issues, with special months going up to 300 000 or so. Jujutsu Kaisen sold over 800 000 copies in march 2022.
And when a new Asterix comes out, it will usually sell around 1-1,5 million copies in its native French speaking market.
And neither of those other markets is dominated by two UNIVERSES the same way American comics are by DC and Marvel. Everybody else has multiple independent works and different kinds of stories.
D&D would be better if it wasn't for Wizard fans
