Starfield, Hogwarts and possibly Baldur's Gate 3 for me, although the only one I feel any confidence for is probably Hogwarts, especially initially. The other two likely will need many patches and DLCs, and then mods, to really shine, and you never know what the modding community embraces or not.
I will do a new build the gen after Starfield comes out most likely, to get the most bang for my buck. I still play Skyrim AE modded, have the GOG version now but those come out a full decade or so after the originals, so I play the Steam version until then. If there's a GOG release though on day 1 I will buy it full price immediately and all the expansions, I just doubt that happens.
