I already mentioned that the graphics aren’t far from a 10-year old game. Where it differs though slightly is in the models. The models look better. This includes both your character and enemies. At first I was sure they are mostly reusing old models from Diablo 3, but when you fight King Leoric (yes, you have to fight him AGAIN), you’ll see him riding a horse.
Manoruk, a giant lich popping out of a doorway is also a lot of fun.
There are now splashes of blood on the character, and the fabrics such as crusader’s tabard looks better too.
The fights are slightly more telegraphed, I would say, than Diablo 3. Bosses would highlight the zone they plan to attack, and your attack draw cones or lanes as well.
Story-wise, it was a very smart move from Blizzard to release this after Diablo 2 Resurrected, as the story takes place after Diablo 2 and before Diablo 3. So most of the iconic characters such as Deckard Cain or Charsi are still alive and well, and gamers now remember who they are.
And in general, it feels very much like a tribute to Diablo 2. You even visit first woodland, then a desert, just like in Diablo 2.
