Many mobile games instill a fear of missing out (FOMO) in players using special events or designs that can only be unlocked for a limited time. This is especially the case in gacha games like Fire Emblem Heroes where the idea of collecting units is easily supplemented by holiday variants that might encourage users to shell out on microtransactions. Niantic's Pikmin Bloom isn't a gacha game that relies on FOMO, but it has been experimenting with similar ideas.
