I can't agree with that, dear Magnus! The visuals of most units are made at a high level. We couldn't expect the developers to simply copy the art from Heroes of Might and Magic 3 and make it 3D, could we?! As for the magic, the spells simply became less similar to each other, while in previous parts they sometimes differed only in appearance. And some spells were replaced by hero abilities, which didn't exist before. As for the plot, it's not very important to me. The most important thing is the gameplay.
