had a chance to spend a couple of hours on this, the night "Single Battles" are very well done, accurate OOB, gunnery, torpedo attacks, damage control, very immersive and really what I was looking for. They also modeled most of the surface battles in 42-43 in the Solomons. The night is clearer than I would like and the AI plans need to be tweaked (although not bad as is), but no real issues so far.
