I tend to fall back on games that have a setting and possibly a story, but have the main gameplay available as repetitive things to do.

Fighting games

Racing games that don’t have a defined ending

Games like Battletech 2019 which has a story mode and also a never ending campaign mode.

Open world games like Skyrim and Grand Theft Auto, but mostly side quests and doing random non-story things.

My main reluctance for playing new games is learning new mechanics and story with all the interruptions of adulthood. I keep buying them and just planning on playing them later.
