I think if Larian wanted to make a Baldur's Gate 3 and not a Divinity 3 with better marketing, they should stay true to the general feel of Baldur's Gate. The general feel when playing, exploring, and fighting should be as close as possible, and real time with pause is a major part of that experience. There is no Baldur's Gate game on the market that is turn based for a reason. Stay true to the IP.
