Welcome to the forums. Keep in mind there are a lot of options and details we just don't know yet. Many games have highlight effects that you can turn on and off, like Divinity. That way its both accessible for new players and immersive veterans. Although there are some features from D3, you cannot deny the grittiness, textures, and dark corners are indeed a step in the right direction. This is a demo for Blizzcon, expect many changes. I played the Diablo 3 Blizzcon demo 10 years ago, and it was a completely different game to compared what it is today.
