So I was watching some of the gameplay footage. From what I could see, the dungeons and caves are very bright. They keep saying they are making a “dark” game but it looks like daylight in the caves.
Overall the graphics do look less cartoony than D3, which is an improvement, but I think the light levels of indoor spaces needs to be toned down a bit. It would add to the horror elements of the game and it’s more realistic to have less light. My 2 cents.
