Seriously though, I know you said “for the most part,” but I just want to emphasize that there are absolutely story-focused games out there. Games I’d even describe as downright literary, where the entire point is to tell a compelling story and explore some heady themes. One recent one I played like this was Pentiment, which explores some really interesting history and has a lot to say about religion, community, fallibility, family, etc…
And, I mean, lots of other people have already mentioned Disco Elysium and I could write an essay about it but anyone who hasn’t played it should just watch this Jacob Geller video instead.
