Yeah, I was so angry that BG2 was not an adventure in Baldur's Gate ! It is not even in the same country ! It takes place in and around Athkatla, a city in the country of Amn. I am just joking of course.
The full name of the game was Baldur's Gate II: Shadows of Amn, since it has an expansion, but everyone just calls it BG2 and no one cares that it is not really a story about Baldur's Gate. To be fair though, it was a direct continuation of the story of BG1.
BG3 uses the same universe, same region as BG1, it uses the same lore which includes some core issues (the 3 evil gods) from BG 1 & 2. I recommend the Youtuber Harbs Narbs who summarizes the clues : https://www.youtube.com/channel/UCD7GydJQaD7Lnaew1RYsdpw/videos
Sure, Larian could add a subtitle as the OP suggest. Why not. If it can appease some.
