NYGM and Tonnage War are the same thing. Did you mean War Ace Campaign?

Real U-Boat was the first supported supermod, and GWX and NYGM have both gone far beyond what was accomplished at that time. People who use NYGM are vastly enthusiastic and like it the best. People who use GWX are also vastly enthusiastic and like IT the best.

You need to see for yourself.

@rascal101: I think you'll find that people "using both" are actually using them in separate installs, not as a combined game. Those who have tried loading one on top of the other have ended up with no game at all, and having to re-install SHIII.
