I actually want to give the campaign a whirl. You're right, what most people REALLY want from this is an Atlantic campaign mod. But I'm actually looking forward to taking my Uber-monsoon-boat east and commanding task forces to create big ol' fleet battles and convoy slaughters
The appeal won't last long for me, but I REALLY welcome the engine updates and I look forward to what it brings both in terms of mods and in terms of what I suspect may be future releases that REALLY utilize some of the new features (like being able to coordinate surface units *cough* DC2 *cough*)
