If that's your logic then the average spartan surpasses the training equivalent of the Duke. He can't jump from a Pelican passing the sound barrier; flying through the mesosphere layer while steadily controlling the heartbeat and taking out enemies on the ground one by one. This is my opinion and it's not based of any rating everyone else is occupied wallowing in. Plus the alien invasion is on a much larges scale huheu.
Now, I don't hate Duke Nukem, I loved it as a kid. I'm down with it being released and I want to play it.
This is easily compared to the controversy between Runescape(Duke Nukem) and Wow(Halo). I think it's stupid and they both mostly have nothing in common besides the fps and alien invasion. I'm with Halo on this one mainly for its bold, heroic, and legendary story line.
