Helldivers 2 is good at this. Their items are all non-FOMO (you can always obtain them once they appear). What FOMO they use is the fear of missing out "epic" events and participating in them yourself. Something you don't "collect" as much as become able to remember later on.

Then it is fun to see that crafted by your nick item on hat fortress from 20y ago. or have elders scroll online items that are not in game anymore if you didn't get it before reforks or similar. I don't go with FOMO, I go with enjoy the collection part of game and nostalgia.

When there is older game that has it records of random items that are not in game anymore or go on cycle on every five years or anything random that make item unique or rare, I like it if I have get it then. I can use money for them if it not fuck up euros spend / time spend ratio. 1/

I used to try to stay up on the new Magic: the Gathering products coming out, but then Wizards just ramped the rate up too high and I gave up and now I spend less on MtG than I did before.

I've actually been following this gacha game for over a decade now but I've never really played it since I often said: "The best part of this game is the fanarts."

in case of FOMO games, i learned that the best movement is not to play

FOMO comes off as even more foolish when 90% of the time the item only provides some niche benefit you'll forget about in 2 months time or less, so you're shelling out a new-game's worth of cash for a digital trinket you'll likely won't even remember weeks from now.

Blizzard found there where people willing to pay $90.00 for a mount. All because they missed the chance to get it in game during the Battle for Azeroth xpac.
