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.
I agree, we don't need to touch on the narrative or story really much at all. It's not going to make any sense unless you are really closely following it anyway - which is a very small percentage of people who are mainly already on this forum. WE don't need marketed to.
Show people Baldur's Gate, maybe some familiar vistas from the original that have been lovingly re-created in this engine. As dirty as it is - nostalgia works and people who played the original will be hooked on the idea of seeing the updated version of the city. Maybe highlight some aspects of the city that are not tied to the main story, but just exist.
