They probably spent more time and money on DRM than on physics and AI logic combined. My latest irritation is trying to put together a balanced mission, at one point I had 10 Northhampton heavy cruisers ganged up on a single Furutaka. The Furutaka was dead in the water early on, but with 90 eight inch guns against six that thing just would NOT sink. Instead half of the Northhamptons were DIW and the other half sunk after two hours of hammering. "Hit points"? Seriously? Couldn't have come up with better damage assessment than that?
