I have Silent Hunter 2, 3, 4 and 5 played. Silent Hunter 2 was just classic. Silent Hunter 3 brought many innovations, especially graphically at that time. Silent Hunter 4 is not so great, because you play on the side of the Americans in the Pacific Ocean. Silent Hunter 5 is just annoying. Graphically, the last two a lot better than Silent Hunter 3, but the game goes flutes in my opinion. Therefore, Silent Hunter 3 is in my opinion still the best submarine simulation you can get. Here you can really kill hours and it is great fun. Anyone have any submarine has simulation, but it is interested, should get this one!
