-Grittier, tonally darker colors with higher definition and contrast, a return to the colors before Patch 8, and increasing what people liked about it. People are rightfully mad. I've seen the words "darker," "realistic," "gritty," thrown around a lot and just want to add that those features are quite immersive. I've seen comparisons to DOS1, but I would also compare it to the Dragon Age series when they abandoned the whole dark fantasy angle for high fantasy, or how Oblivion feels after playing Morrowind. I thought the slightly darker palette actually drew nice parallels with BG2. Instead of increasing that, Patch 8 has veered HARD in the opposite direction.
-Companions should have something to say to Withers when revived, at least once per companion.
-If we are getting dynamic shadows based on sunlight through clouds, can the clouds change, or can the shadows move from pointing Westward to pointing Eastward over time? Or however Toril rotates with respect to the sun? If there can be full clouds and potentially rain effects, can there be a weather-marking of the days?
-Stop recycling story beats from DOS2. Saw this mentioned by GM4Him that playing DOS2 ruined BG3. It is that immersion breaking. I'll accept Astarion (Rogue Elf who puts a knife to your throat upon meeting, who has a dark personality, and is hunted by the one person who is either his freedom or his enslavement, depending on your choices) and the introduction as nice references to the predecessor game, but further story and companion similarities between DOS2 and BG3 will likely be met with frustration. I know it's late to say it, and many probably already have, but that's a mistake.
-Can there be spots in both the world and the Underdark to use a fishing rod at certain bodies of water to fish for food or items that could be buried at the bottom of bodies of water? Including beaches, rivers, lakes, ponds, etc. Not a minigame, more like the shovel. Probably a dex roll. Fishing could also provoke combat encounters with underwater creatures either waiting in ambush or surprised at your lure.
