I love romances and companion interactions, but now I know from BG3 that they can't carry the game if the underlying plot isn't solid.
I hope if there's a definitive edition some of the act 3 stuff will be fleshed out more, although there's only so much they can do to to fix the main plot at this point.
Maybe it's unfair to compare BG3's plot to that of the earlier installments in the series (which of course have the benefit of being parts of one big epic story focused on one character), but as a huge fan of the old games, I can't help it. The plots in BG1 and BG2 weren't entirely perfect, but they were really focused, with strong beginnings, middles, and ends that were all connected to the main villain. BG3 has too many plates spinning for one game, IMO.
Why would it be unfair?
It was Larians decision to rewrite large portions of the plot last minute to shoehorn their consequence free tadpole superpowers in (which also shows how little regard they had to the plot, story and writing ) and instead focused more on attracting simps with sex scenes and waifu companions.
Financially it was the right decision, but still resulted in a lower quality game once you see past the glamour.
