My impression is that BG3 is still too D&D-ish to appeal to non-D&D fans, while not sticking close enough to D&D rules to appeal to half of the audience they should have. People that wanted a tactical, turn-based game and are ok with the DOS2 mechanics will probably love it. People that wanted a more PC specific translation while retaining the D&D feel seem to dislike it. Right now there's a lot I dislike about BG3, but I do see potential.
For me, the great divide was between isometric 2D games like BG1/2 and POE (technically 3D I guess) and subsequent games like NWN where studios tried to leap into 3D and more action oriented gaming. There's definitely something lost in terms of tactical play and party management when you make that leap, but there's also a lot of benefits in that you gain a wider audience of people that just want to play an action RPG. I think BG3 is so close to bridging this gap in a way that hasn't happened since the original NWN, but they're still falling short. Possibly because of their attempts to also appeal to console audience which would lack the ability to party manage like a PC player could, and I think also because they want to carry over their unique DOS gameplay elements that are controversial.
I really hope they dump the DOS gimmicks and focus on creating encounters that can be solved using D&D mechanics, and then that they improve party management issues that have been a problem since DOS1. Technically, I don't think there's anything stopping Larian from making this a great game, but I think it's management and design decisions that they've chosen poorly on, and they might be trying to be too much to too many people to really focus in on what they need to do to make a great game.
