Actually, I don't believe Enigma Rising Tide is any more ASB-ish than some "serious" and "literary" novels and stories about the early 20th Century. German's wins WW1. Anglo-Japanese Alliance continues and becomes its own block (including the Royal Navy in Exile - sort of wierd, I admit, but cool), The USA grows in power. Three way global power struggle. Compared to Crimson Skies (the PC version which is really neat), Renaissance Fall of Man, Freedom Fighters and Turning Point, Enigma Rising Tide is by far much less ASB-ish.
Technically speaking, virtually any global strategy or war PC game is an AH game - and they are far less ASB than those above. I am currently playing "War Plan Orange" by Matrix Games, an AH wargame which is completely based on real world expectations of the late 1920's. It was a hoot when I sent a raiding force including the Amagi and Akagi (Battlecruisers, not Carriers) to shell San Diego shortly after the Pacific War started. I am partially in control of the Phillipines, China is still neutral, and I am hoping the British and Dutch don't get frisky. Unfortunately, the incredibly huge US battle fleet is steaming to an advance base at Rabaul (lousy French!) and it is only a matter of months until they move on the Marshalls and I get crushed.
