I think when you have nothing good to say about something people love and is getting rave reviews then the problem isn't the game. I think some people elevate their own disappointment - at even minor things - to hyperbolic levels and then lose all objectivity.
And it's unfortunate, because objective responses are valuable, it allows you to focus on the issue. When the issue is "everything", also vague and "despite the evidence to the contrary" then those responses have no value.
Being objective, overcoming your own bias is a skillset, some people have it but the vast majority don't seem to. I can't imagine what it must be like, horrifying I suppose, of being captive to your own emotions.
For example: There are things I actually like about Starfield - the ship design system, while a tad buggy and needing better labels on modules, is absolutely groundbreaking and a lot of fun. Designing ships and then walking through them was the most fun I had with the game.
Also the combat itself is not terrible - that IS something mods can improve on because the bone structure of THAT system is good. The rest of the game is quite bad, and it's a bone structure problem. Unfixable. When the universe isn't real but just set-dressing you are basically building on sand.
Comparatively, the bone structure of almost all of Bg3 is good, and so I know the majority of things that need improvement can be improved over time -
With the exception of multiplayer which I am not sure about. It may not be possible to EVER add GM mode to multiplayer and the ability to build additional modules- which is unfortunate because that was a huge draw of the game for me. I mean I started a multiplayer guild and put untold hours into that - now I may as well abandon it. It's sad but Bg3 is still a great single player game and a brilliant game overall.
