I just played through the battle at Kaer Morhen. It is probably the best battle scene I've ever played in a game. Some new mechanics like Triss throwing sunstrikes Invoker style from above while playing as Ciri was epic. The cinematics were wonderfully created as well. The start of the battle was also good and closing the rifts in the wilderness, something which Dragon Age Inquisition should have excelled at, created the initial tension well.
The Witcher guys have likely hired top level directors because from what I've seen in the battle, scenes of that magnitude cannot be created by mere 'medium' level devs like CDPR.
This is downright the best game I've played this decade. Better than Xenoblade even (which was previously my GOAT).
