One of my main heuristics for if a videogame is worth playing is if it only works as a game. As in if you transported it out of the medium, it loses a lot. The adaption can still be good, hell, the game can still be good but I don't think they're interesting in the art form that is videogames.
My main example here'd be TLOU. The netflix adaption was pretty much a hit because of course it is. The story is entirely linear, it's very clearly subdivided into combat -> exploration -> story, allthough sometimes the order changes. It's all polished to a mirror sheen, the gameplay is fun, hell, the brutality ties in thematically instead of being a back-of-the-box selling point to edgelords (allthough it is also that) but functionally it could be a movie or a series and it is and it works.
So whats your videogame that only works as a videogame, and most importantly, why? I think Disco Elysium is the free bingo square for this community on this one and the reasons are endless, but I'll start with something that surprised me recently: the new Hitman games.
They have movies but they're shit, all the comics and tie in novels I assume are for people into hitman lore because the story isn't really anything to write home about - mostly existing to get you to next location - but the the experience of playing hitman can't be recreated in another format because the interactivity is such a big part of it. I mean sure, "shoot someone in the head" basically always works. It's one of my main criticisms about a lot of games I have that give you a whole host of options to tackle a mission which all pale in effectiveness to "have a bit of aim and do headshot with the starter pistol" but somehow it's way more fun to hoist rich dipshits by their own petard.



Lots of anti-games work for this. DayZ, at least, the hook of it's original experiment, cannot work without the interactive layer and other players.
