I don't know how feasible it is, but I'd love BG3 to have a more "realistic" lighting system. As in the game recognizing light levels from what the light source actually shines on (an how brightly) rather than "visual" and "mechanical" light systems being separate. (Ok, I think I described it very awkwardly. But I remember Swen saying that there's some light patch added by artists that the game doesn't see as light, and I remember similar reports by players. So apparently there are two light systems.)
