Reminds me a bit of Daiteikoku, the AliceSoft sRPG/visual novel game. That re-writes WWII into space, with Japan defending China from evil Western capitalists (by invading it). Oh, and Hitler is some sort of pop-idol girl.
And I thought, "well, this is obviously comedy, someone just dicking around; it's got nothing to do with reality ..." - but I played it a bit and I just could not stomach it. Which feels a bit hypocritical if I looked around at all the incest, rape, loli stuff and whatnot else one might be outraged about; and of all these things some sort of parody thing bugged me?
But even knowing that I couldn't get over it and I fear this'll be exactly the same ^^;
