The Masquerade glorious, but it looks nice. You can rotate your character via two small arrows added to the paperdoll gump. For everyone who ever wanted to know if their character's ass is fat, now they can find out. I was amazed to find my demo Avatar, Edward, had a very hairy back and some tire marks on his drawers. One last little cool touch added to the paperdoll was your character moving along with your actual in-game avatar.
Daemons look very slick.
Mongbats, yes, mongbats, have a great look. When agitated their wings expand a good 2-3 tiles to their sides. Also of note were ice trolls and Gazers. A brand new land mass with brand 'stuff' . While most people will be excited about the graphics update, the most overlooked part of the expansion is the new lands included with the snazzy graphics.
