You will meet and get to know many new characters, and encounter some of the legendary characters you know and love.
Most importantly, you’ll learn how their stories have evolved. And as you play, you will heavily influence their fate.
Hopefully this will satisfy those complaining why it is being called BG3. But I am sure the "photo-realistic realisation" is still going to chaff.
I think the 2 biggest concerns are that:
1. The overall aesthetic did not look/feel like Baldur's Gate, and I'm not even talking about the fact that it's in 3D now. The atmosphere, the sound, the tone, even the UI, none of it really looked like BG.
2. The lack of rtwp combat. Yes, it really is that big of a deal, as it is a fundamental feature of all of the old Infinity Engine games, and even the NWN games. You could even look at it as the feature that separates those that are looking to play a BG game and those that are looking to play a 5e DND game set in the BG world. I say just add the option to play either turn-based or rtwp.
