FOMO stands for Fear Of Missing Out.

I've tried playing some JRPGS because they are considered classics and detective games like LA Noire before realizing the genre just wasn't for me.

I've also been stuck in the mentality of if I want to play a game in a series I need to play the prior games. I'm doing this currently for Deus Ex, the Witcher, and Splinter Cell. I guess I'd consider that FOMO to a degree.

Edit: I meant FOMO as in the fear of missing out on something relevant. Not necessarily something that is intentionally being time limited like raids or micro transactions.
