I admit the superiority of the sloped armor at least in CMBO terms but, yesterday I ve found an article which is partially negating the game engine.
here is a excerpt:
The armor of the Tiger I was not well sloped, but it was thick. Here is where many fail to understand that, in terms of World War II tank warfare, thickness is a quality in itself, since armor resistance is mainly determined by the ratio between armor thickness and projectile diameter (T/d). The T/d relationship regarding armor penetration demonstrates that the more the thickness of the armor plate overmatches the diameter of any incoming armor piercing round, the harder it is for the projectile to achieve a penetration. On the other side, the greater the diameter of the incoming projectile relatively to the thickness of the armor plate which it strikes, the greater the probability of penetration. This explains why the side armor of the Tiger I, being 80 mm thick, was so difficult to be penetrated at combat ranges by most Allied anti-tank and tank guns, whose calibers were overmatched by the thickness of the Tiger I armor. The quality of the armor was another major asset of the Tiger I, and it can't be emphasized enough that the Tiger I was a very special kind of Panzer, since it had the best quality of everything, compared to any other German tank. The rolled homogeneous nickel-steel plate, electro-welded interlocking-plate construction armor had a Brinell hardness index of 255-260 (the best homogeneous armor hardness level for WW II standards), and rigorous quality control procedures ensured that it stayed that way. The Tiger I's armor was much superior to that of, for example the Panther, which armor had a much higher Brinell index, and consequently, was very brittle. The Tiger, as a side effect from the usage of this special armor, also was a very expensive tank. The nominal cost of a Tiger was 250,000 Reichsmarks. In contrast, a PzKpfw III cost RM 96,200, a PzKpfw IV RM 103,500, and a PzKpfw V Panther RM 117,000; all these figures are exclusive of weapons and radios.
