I think that Silent hunter 3 is better than AoD.
Aod was very good for his time but we have now a game that do about the same things and more with better graphics .
only few things remain from AoD with is not possible with sh3:
wolfpacks, bdu ordering new patrol grids, and bilge water gauge.
I have a copy of Cod that works in windows, but runs a bit fast in my computer
I thin that sh1 was a very good game too.
a great campaign ( start departing in manila and finish the patrol sinking ships in the same port that is now japanese), good damage modelling ( the water in the engine rooms could damage the e-motors and diesels) , very good graphics, and enemy submarines .
