Absolutely. I think that a better advertising choice would have been to focus on the city way more. The city looks GORGEOUS and if the whole trailer had been focused on presenting it, showing off some of the stuff you can do in the city, maybe some cool people and places, I think that would have gotten general people way more excited to explore the city. Since he's a lord, you could even still feature Gortash. Instead of focusing the whole trailer around who he is, have him almost be a presenter of sorts maybe.
The game is CALLED Baldur's Gate, tell us why we should want to go there! Though frankly, Act 1 has entirely failed to sell Baldur's Gate as a place so I shouldn't be surprised their marketing does the same.
An alternative thing to focus on is the amount of choice present in the game. For all my issues with it as a roleplay experience, I'm not even going to pretend BG3 doesn't have a truly impressive amount of flexibility in what you can do. Showing some of that off would have set it apart from all the more linear games at the showcase.
