Steam do not allow long reviews, so I posted my review on my gaming website: http://dirtyape.rocks/my-world-at-war-review/

But I will say the conclusion.

All in all, Call of Duty World at War is one of the best COD games out there. It is truly fun in all modes of play which is not something that can be said for the rest of the series. The campaign holds no reservations, it has the strength to depict World War 2 In the most brutally honest way it can.

While the overall story and characters aside from Reznov could have been written better and in a way that makes us care, I see that was not Treyarch’s goal with this game. It is not so much character driven. They wanted you to think about this war, that wanted to show you what it was like. Nazi Zombies spawned from this game, so much lore, fun and creativity that has blessed the COD series for better or worse.

Having the last profoundly good WWII multiplayer in the series, and the way it took the best elements of Call of Duty 4 and replicated them, turned into a multiplayer that pretty much every fan could enjoy. I want to play more of this great game than talk about it that is how good it is.
