It's worth the $10. I modified my saved game file to promote me to the highest rank to mess with all of the support assets. I have now become addicted to directing crusiers and merchant cruisers all over the Indian Ocean sinking convoys. I spend more time setting up an interdiction point with a merchant cruiser than I do with my own boat. If I run into something, fine. If not, I have a fleet of pirates to keep me busy. Aaargggh!
