Tabletop Gaming Hot Take
@adeptomega Hmm. Maybe we're thinking of different categories of thing? I'm thinking of the whole genre of story-driven oneshot systems that are designed around deeply exploring a particular emotional or interpersonal topic. (See: basically everything published by Buried Without Ceremony.) Those can often say everything they need to in 3-4 hours, and tbh playing longer than that is something I'd find emotionally exhausting a lot of the time.

@adeptomega although on consideration, those arguably are borderline falling outside the umbrella of "gaming".
