I agree that the color pallet is a little too loud. I think the art style in general just kind of detracts from the whole narrative and vibe.
There’s pretty wide consensus on the forums that the urgency of the tadpole story conflicts with the actions immediately after the nautiloid. I don’t think this is a huge deal because it can be fixed with some dialogue changes just to let you know about the stasis early on. I think they’ll do this
I think your observation about the turn based system making the most of every character is very astute. Playing real-time one person controlling 4 people against a dozen or so opponents controlled with the efficiency of a computer and it’s going to be a blood bath. Larian would basically have to rewrite/rebalance every battle to make real time a possibility. There’s no reason to do that when we already have a system that works.
Strat-Edgy did a decent review of BG3 and his summation of the combat is pretty much where I’m at. It has some flaws but it’s a great way to demonstrate the role of your character
