Call of Duty is easily the best World War II game I have played. The design of the game is very brillaint. The game pulls you in and actually makes you feel like you're trying to survive.
Gameplay: There are 3 different perspectives to this game, so to speak. You play through the game as a United States soilder, a British soilder, and a Russian soilder, all of which have unique missions and mission objectives. The realism this game has in it is astounding. Playing this game draws you into thinking you are actually fighting in WWII.
Graphics: The graphics in the game are really good. The details in the buildings and other surroundings are really great. Plus, the guns look like guns you would actually find from WWII.
Sound: Not only does the game bring in epic music, but the sounds (such as explosions, gunfire, far off noises and voices) all make you feel there, like you are the character. It's amazing.
Replay: CoD has very high replayability. I have already played through the game 3 times.
Overall: I would say buy this game if you have a gaming quality PC. And if you love shooters, I think you will definately see this is one of the best you will have ever experienced.
