Hitler is not in the game because we was a lousy leader. He brought his country to a peak for a very short time then had it all come crashing down. By the time he was done with Germany, the cities were rubble, the economy was in ruins, and the country itself was split in two. That was his legacy. Stalin on the other hand turned his country , which at the time was decades behind all the other Western nations, into one of the world's super powers and though not quite as influential as it once was, it still can be counted as one of the more advanced and powerful nations in the world. His legacy still remains today while Hitler's required alot of mending to overcome.
