While I wish you were right, something tells me that even with an 80-100$ pricetag it'll still be one of the most successful games ever released.
Look at diablo4, for example. 70$ base game, 90 for deluxe, and 100 for ultimate plus mtx in the store at stupid prices. And apparently it's sold over 6 million copies and made over 600 mil in revenue in the first week. And it's not even a good game, in my opinion.
Exactly. If there was only one currency for all old content, everyone would just do the most efficient farm and buy everything that way and not interact with any of the related content.
