Okay so the games have to be of a certain size, I understand your list a bit better now
.
I can definitely see an argument for not including the in-house games by ND Cube then, since even though they are full releases unlike Grounded or Pentiment, they are still smaller in scope than other titles.
But wouldn't the Xenoblade and Splatoon games count as big productions? Ring Fit was a major project for them as well.
I'm still not sure on the importance of "in house" though. One could argue that Luigi's Mansion 3 wasn't a big in house game at launch, but now it is. But that doesn't really impact the player in any way.
