For full price games on release? No, they really aren't.

People always says "cosmetics are fine". They aren't. Cosmetics are gameplay. Humans love looking cool. They NEED it a lot of the time. The entire fashion industry wouldn't exist if looking cool wasn't a major part of human psyche. These MTX wouldn't sell if it wasn't. Locking all or most of the interesting looks behind additional paywalls is bullshit. And it's not OK. I don't engage with games that do that. There's plenty to play that don't abuse their customers.
