One thing I've been reading a lot about the Diablo IV beta is how snappy the game is. The combat, loading screens, and menus are all just snappy.
Blizzard was known for what we called, "Blizzard polish" and how far we've come to the point where a game of theirs works like the way their old games used to, and we're all genuinely surprised by it lol.
