SH3 has a variety of choices of supermods, which allows people to choose their preferences. There are 4 big ones you should be aware of. (please note that I've only played one of them).
-NYGM (Not Your Grandmother's Mod) focuses on enhancing the challange and difficulty, while pushing aside graphic improvements.
-GWX (Grey Wolves eXpansion) strikes a balance between difficulty and graphics.
-LSH (Living Silent Hunter) tries to keep the atmosphere and feeling of the original game, while massivly improving the graphics.
-WAC (War Ace Campaign), the newest one on the forums. I don't actually know much about it, but it seems to try and merge the beauty of LSH with the challange of NYGM. Someone else will certainly be more detailed than me.
All of them add new ships.
The one I play is GWX. The thing I love the most about this mod is that it has
atmosphere, plunging you into the grime of submarine warfare very effectively.
My advice is to do what I do not, and try them all. See which one you prefer.
