That’s not what fomo means. I have a bad case of FOMO right now with Genshin Impact. I genuinely like the game, but it forces me to login twice a day with the resin system (basically energy that accumulates over time), otherwise it caps and I lose progress. Also a lot of their content is in the form of limited time events. They do this for the obvious reason of it being extremely profitable. This is why you should be very cautious about getting into live service games.
