I haven't played fortnite, but Folding Idea's analysis of Fortnite [0] suggests that it does. As a specific example, it presents only a small subset of the items available to purchase any given day. This allows them to obscure the relative prices in a way that would not be possible with many more viewable for comparison. A microphone hammer is 800v today. How does that price compare to a gold hammer, or what was its price two seasons ago ?
If I recall correctly, items are priced based on their rarity, which doesn’t change. So an uncommon thing is 800 vbucks (~$8) up to 2000 for a legendary item/skin.
Imo the shop isn’t as much of a dark pattern. The game is just constructed in such a way that it’s constantly engaging and fun from beginning to end, and very good at playing with friends.
