It's being compared to Starfield (instead of TotK, A6, FF16, RE4, Dead Space, etc) precisely because it's low hanging fruit. A not insignificant portion of the internet is intent on making it the face of anti-AAA sentiment which falls apart if you acknowledge BG3's flaws or Larian doing the same thing, so they either pretend it doesn't exist or downplay it.
I'm 75% sure it's part of proxy console war.
Because the other game is literally available on console first.
BG3 wasn't. It's PC game first but got dragged into this comparison war.
I mean what we could actually compared between BG3 and Starfield apart from writing? - which always comes down to: I like this one better.
Starfield is not an RPG, it's action adventure with RPG elements, TOTK is hack and slash 3d platforming/puzzle with RPG elements, FF16 is hack and slash action adventure game with rpg elements - none can be compared with proper RPG like BG3 is.
