For me there are a couple.
Hades (2020) - I'm not in any hurry with this one. I'd get it if GOG starts to sell it, otherwise I'll wait a bit more.
Outer Wilds (2020) - I'm getting impatient with this. I'd like this more on GOG too, but I think I'll just buy it when Steam winter sale comes.
The Guild III (2022) - quirky trade/life sim game and I have some fond memories of the second one. But that had quite a few bugs even long after release and I hear the third game still looks unfinished so I'm patient.
Morrowind and FTL. Both I revisit every couple of years.
I suspect Stardew Valley might become something like that too, but I only had one cycle of stopping and coming back with it so far.
