However, most of those games mentioned, BG3 included, while the reactivity makes the game more immersive, it doesn't really change how your story/game plays out (Which goes against why he chose BG3).
No he didn't. Please, watch the video, not OP post, who have written things that Tim didn't even say. The exact quote is once again:
I particularly love character customisation in Baldur's Gate. You can make widly different characters, that behave widly different in the game, and again, there is a lot of choices and many reactivity to those choices
You can customise character a lot, you can make variety of characters who will behave and play differently, you can solve pretty much every problem multiple ways (there for choice) and game does roll with what you do.
Nothing he said praises branching narrative. He didn't even say reactivity is particularly outstanding. But the game does offer a wide range of tools to create the character you want, and express this character during the campaign.
