Regardless of who's to 'blame' I still think they should have gone with Baldur's Gate: [Insert title here]
It still strikes me as incredibly lazy to just name it Baldur's Gate 3, and it's almost certainly just a marketing scheme from WotC / Hasbro. Nevertheless, we're a bit past the point of changing anyone's mind about it, I think.
Yes I agree this was a missed opportunity. "BGIII: <subtitle>" would have calmed a lot of currently-angry BGI/II fans while also staying true to the naming style set by BGII: SoA.
I don't know that I'd call it a 'missed opportunity', but this is at least an idea I can get behind as opposted to people just drawing a line in the sand and insisting 'it shouldn't carry the Baldur's Gate name'. I thought something similar (subtitle) in the midst of reading all the various kerfuffle the past few months in various places, given BG2 also doesn't involve BG technically at all and at least does reference the area its based around.
It's also not impossible that, before release, Larian might reveal they're doing this....but we'll have to wait and see what happens.
