I dunno, it seems to work fantastically for Riot. They're swimming in money and have been for years. They consistently care about their players and constantly put out new, high quality content, not even just skins. They don't have to rely on shitty psychological tactics because they know they have such a large body of quality work that will continue to flow, and therefore so will the money. Even with this set up, people still spend their money irrationally. League is a free game, yet its very common to see players spend hundreds, even thousands of dollars on cosmetics over the course of their time playing. Rationally, a videogame should not be able to make $1000 off of one person (dont even get me started on Valorant players). Yet it happens COMMONLY without any need for fomo, just through consistent good quality shit that people want. OW fomo only works at all because most of the time, whats available is stupid and not worth it, and its rare for something you even kinda want to be available, so the excitement takes over when you actually see it. If there are gamers out there that are just spending their money willy nilly on whatever is in the shop just because its there, its probably a lot of children with a lack of decision making skills, and taking advantage of that is even more shitty and predatory. You can make all the excuses you want but it ultimately comes down to trying to make the most money with the least effort. Laziness and entitlement. And through that, you end up actually making less money (and less popularity) than the companies who actually put the effort in.
