After watching the trailer a few times I realised why the animation and character models reminded me so much of Infinity engine games - the 3D models behave like 8 directional 2D sprites!
I have always assumed that having 3D models in the game would mean character turning would be smooth rotation (like in Diablo 3), but either through a limitation in the engine or deliberate choice, Obsidian have decided to limit the viewing angles of characters and mobs to just 8.
Has anyone else noticed? Has this been mentioned before? What do you all think of this implementation?
