And you? Have you put aside a game that was super important to you for years, decades, but that has become uninteresting?
I think I might distinguish between games that have become uninteresting because I've changed in my interests and feelings about games, and games that have kind of decided to make themselves obsolete or uninteresting. It is very much a judgement call and there's some overlap for sure, but I feel like a distinction exists.
Like D&D seems to have become uninteresting to me and most of the people I play with (after playing a fair bit in the pandemic), and I don't think that's wholly D&D's fault. I think it's more that we changed, and other games appeared, not that D&D decided to become obsolete. I do think 2024 missed a trick here by basically doing few meaningful updates and being more of a curate's egg than it had to be, but it's clearly not suicidal or anything (indeed, not changing probably helped in a lot of ways). So that's the first kind imho.
But Shadowrun we kept going back to every few years from 1990 until maybe 2016 until it became obvious that it just didn't have the juice anymore, and I don't think that's because of our change as much as two things:
1) The modernizations of the game were not making it better, just changing it almost for the sake of change (and to a curiously... Teutonic... vision imho).
2) The society it portrayed was weirdly irrelevant-seeming (where Cyberpunk 2020 almost seemed more relevant in some ways), with a lot of concerns and ideas that that could be relevant, but were set up in such a way that they were not. This was actually an issue in the 1990s even, but time passing made it worse. This is a hard one to express exactly because on paper, SR should be more relevant than ever. But it just isn't, because the on paper concerns are not really what the game focuses on in mechanical ways, in terms of what the setting details, and in terms of what the adventures are about. Like being SINless in a society like that should be a much bigger deal than any version of SR portrays it.
I'm just not into it anymore, and unless they rebuilt Shadowrun from the ground up rules-wise and frankly rebooted the setting back to something more like the 1E/2E-era version (but updated and re-envisioned, I'd hope), I don't think that's going to change.
I used to care deeply about it, so kinda hate to say it but I think the entire oWoD finally hit this wall too, if I'm honest. 10 years ago I would have still absolutely played in or ran-if-requested any oWoD game pretty much, albeit it would have been kind of retro/nostalgia in some ways (and I'd 100% have set it in the 1990s). This includes the "new oWoD" or whatever we want to call it, which seems like it's tried to modernize the oWoD but singularly failed to do so successfully for me, leaving it in this weird juiceless (to me) state where it doesn't have the fire or passion or sheer 1990s insanity of the actual oWoD (including the 20th anniversary versions), but also has failed to create something new and exciting and 2020s-feeling.
Oddly I would say the nWoD has not been as badly impacted. I would still play Vampire: The Requiem, for example. It honestly feels more modern and interesting to me than a lot of the 5th edition stuff.
