While the lack of laughter can be from depression or stress (the podcasts I used to die laughing from only get an actual laugh out loud moment every once in a while now), I feel like most story-based video games that do humor try too hard nowadays and it doesn't land (like outer worlds)
Most of my laughter in video games, personally has been from interacting with other people. Valheim, Helldivers 2, REPO, overcooked, stardew valley, etc...
Probably the last single player game I laughed with was A Hat in Time or something.
