You're implying that Larian have actually been evolving with each game. Which is not necessarily the case
I wouldn’t only imply this, but state it clearly.
Divinity 2 already had the Freedom of action, but there was little social conflict involved.
Dragon Commander added the hard social choices (in a very in-your-face way: choosing a demon’s power over your wife; it’s even darker than BG3).
DOS added the uncertainty in social interaction — even with PCs.
And BG3 pulled all of these together into a consistent whole (in my opinion) in AAA production quality.
