Did we read the same article?
His starting comparison of Marvel to "Olive Garden in Italy" is weak, but not unrelated, so I'm not quite sure what you are talking about.
Proof that the game is doing poorly in the UK and Japan, which adds to the argument he's trying to make (those markets are not the ultimate determinants of Marvel's success, given that they have historically done weak compared to the US).
Unlike you, I'm not gonna end my post with any silly snark attempt.
He implies that Media Create (or as he terms it, Media Crate) numbers are fake and also fails to mention that while Marvel games do worse in Japan, this one sold 10% of the numbers that the MVC3 did. That's not just "not great", as he puts it, that's historically bad.
MVCI was outsold its first week by Destiny 2 and NBA2K in Japan. Abyssmal isn't even a strong enough word.
