a bit off-topic, but I'd like to point out a great new (and not so big) mod:

just recently I found this great sound-package for SH3.
it has very immersive sounds for: the diesels, the electric engine, the periscope, the torpedoes and their hatches, the ballast-tanks, the rudders (!) .....
even a speech-pack is there (in german).
when diving you get a response: "Tiefenruder ausfahren!"
it's simply awesome!!
