I'll repeat my comment from !aom@lemm.ee:
Gonna be honest, I have mixed feelings about this.
On the one hand, I do agree that it's kinda shitty to charge $6 ($8 here in Aus) for something that was basically the thing people already had in the original game.
On the one hand, the description of it as "22-year-old JPEGs" is wrong. They're at the very least upscaled, but certainly in some form higher quality than the originals. There's also the fact that they're completely optional and unnecessary. They provide nothing but cosmetics, and not even cosmetics that you see in important places like character models. I also think it was primarily intended as a small added bonus for people with the Premium Edition, and to me the Premium Edition is a no-brainer for reasons completely unrelated to this. It costs like $20 extra, and includes the first two upcoming expansions free, each at $15 (or similar maths to that), as well as the Freyr god pack (like $10?). It's able to be bought stand-alone, but I don't think that's really what's intended.
Still, yeah I really think trying to upsell with this pack is kinda penny pinching in a way I wish they wouldn't do things.
