Yeah, bumping the Motherland Calls and moving the Kremlin forward stinks. At least rename the Kremlin Red Square I guess. I am excited for the Red fort, though, but they could have included it and both of the above wonders.
As for an Autocracy wonder: Prora is ridiculous. The EUR as a whole is pretty bland, but standing beneath the Palazzo della Civiltà on a brisk day, with the wind whipping around it is quite overwhelming (not in a positive way, of course). So the Palazzo would have been a better pick in my opinion, or the Valley of the Fallen (never been there myself). Either way, an Autocratic wonder from a Romance country better reflects the cultural victory potential of Autocracy than anything Nazi. The Nazis just produced overly-'realist' bunkum, but Italian Futurism and many of the mid-20th century cultural products of the Hispanic world are very artful.
