I could consider myself one of the people you speak about,I don't see any BG franchise vibe on this game and I'm saying why and offering what I think are pretty reasonable solutions keeping in mind the dev's take on the game,I've seen (I think) every interview with Vincke and Mearls and what you say is kind of true,and I expected as much. I knew Larian,I knew what they wanted to do with the game,but sincerily,I expected to see something that reminded me that this game is BG3,the next installment of the bg saga/franchise (that's how they sell it,if you have seen their presentation and interviews you should know)
I've said it already you can use de DOS engine and still make it look more BG
Of course there's pople who is going to complain for ever no matter what you do,but this is not the case and my point stands,it does not matter that BG is based on D&D because the moment they started to add numbers to Baldur's Gate it became a franchise,and every game of a franchise has to be recognizable,that's a fact. That's the reason they didn't add Dark Alliance to the mix and created it's own franchise. Baldur's Gate descent into Avernus has the name BG because the city is relevant but it does not have a number because is not part of the franchise.
