It is a point of discussion in a extraction game in which it is all or nothing, to have storage which guarantees you to extract with items in the first place.
But I can understand the decision from a “it is still a game and that could be just too frustrating” point of view. But to sell extra spaces for rl-money is just ridiculous.
It may not be “pay to win” as you can still lose in a gunfight etc. But it is sure as hell “pay to have unfair advantage”.
And I think the rhetoric should shift to criticizing that in games. Because publishers can “win” an argument on that technicality.
Every time I play with a friend who has the EOD edition and she gets to take more back to base then me after dying, I get a little frustrated.
