So far, the series has taken us almost as far as the year 2030, which really isn't that far into the future. Sledgehammer could make bringing CoD to a far-but perceivably realistic-future a setting that could work. In previous Call of Duty games, players have already spent some time floating around in space, shooting zombies on the moon, and getting their hands on super-advanced tech. Look, I know that this is pushing CoD close to the Halo zone of FPSs, but going into outer space and having futuristic weaponry isn't too farfetched for the series. And while a CoD version of the battle could be one of the most epic missions ever, showcasing conflicts like these could give the developer a chance to show how much war actually, really sucks. The Battle of Hamburger Hill was one of the most hard-fought and tragic of the war. But there wouldn't be a lack of huge battles. Enemies could use guerrilla tactics in the jungle, hitting your squad in the middle of a patrol, then disappearing into their dug-in hideouts.

What's most interesting about setting Sledgehammer's game in Vietnam is that the jungle environment and enemy Viet Kong tactics could make for some intense engagements. Some of the greatest moments from the old WWII games in the CoD series came from being a participant in the massive, famous battles from history, and now I think it's time that Vietnam gets the same treatment.

We still haven't experienced the conflict from the perspective of the average soldier holding his own in the jungles of 'Nam. Black Ops may have dabbled in the Vietnam War, but that was all behind-the-scenes, secret operative stuff.
