Guys, have you ever played Command: Ace of the Deep or Silent Hunter 3? You play the bad guys. You play a U-boat sinking civilian shipping and warships alike. 99% of times, you'll die, all hands lost at sea. The odds stack against you the longer you play and if you survive, guess what, you've still lost the war.
It's the only type of game in which playing Axis, especially Germans, is acceptable, because there is an aura of nobility and respectability to the U-boat service in WWII as the Kriegsmarine was the least Nazi branch of its armed force. Many Kaleuns were in fact crypto-antinazi, some of them were vocally mocking the regime under the protection of their Hero status.
"Teddy" Suhren, for instance, came back from his last mission mockingly asking whether the Nazis were still ruling Germany, and when learning that they did he ordered his crew to turn around and return to sea, and this was in 1942. This became widely known in the Uboat service, and the guy got no consequence. In fact, BdU would routinely cover-up for Kaleuns and U-boatservicemen on furlough creating mayhem, getting drunk, whoring around, insulting the regime, or punching officials on the nose.
But this was offset by quite a few officers and underofficers who were rabid Nazis of their own. One Kaleun got shot for cowardice and defeatism when he was denounced by his own pro-Nazi First Offficer.
