Harry Potter was the series that helped me discover I liked fantasy stories. Since then I've read a bunch more, many I've re-read, Discworld being my favorite. Haven't gone back to Harry Potter once, not counting the movies(EDIT: Then Hogwarts Legacy of course, it was the realized dream of a HP game I always wanted as a kid). The idea of someone reading those books and not wanting to try anything else similar baffles me.
Stalker 2 if that counts and whatever comes next for Half Life.
Even if stalker turns out not great, the original games weren't amazing either. I just like the setting a lot. And Alyx shows me Valve has that spark for the series again, so I'm looking forward to seeing what they do with it, VR or otherwise.
Would not have been surprised to see Blizzard on this list because whoever they've got doing their writing now isn't any better.
