I already know your thoughts on this game and having played the game throughout and played all of the game modes thoroughly, I must think that you are incorrect in your thoughts. We have already had the discussion over the length of the campaign but I have to think that you are wrong to assume that this takes away from the game, even if you believe it to be true. So, here is my review of the game.
Good Points:
The campaign is fantastic. It is brilliantly detailed and just fantastically diverse in every single mission. You may have heard about all of the different types of mission but to be very honest with you, I have never seen a shooting game that is so diverse. For example, the first mission is a normal shooting mission and training exercise. The missions that follow are just completely different. For example, the mission that is shortly after that is a mission where you have to climb a rock-face and then use stealth skills to slip past a few guards throughout the mission. After that, you have to escape from them on a snow-mobile and it just proves the point that you wont get bored with the game very easily.
Another great point of this game is the level of detail that the developers have gone to to ensure that every aspect of the game is as enjoyable as you would expect this game to be. They are extraordinary and every mission is a treat to behold. This is also true of the AI. The AI is extremely intelligent and will flank you at any opportunity. The same is true of the AI that makes up the rest of your team. Consistently moving towards the goal, instead of letting you lead the way all of the time means that they have at least tried to make the game a more realistic game than the last.
The enjoyability factor if this game is just massive. The game modes are so expansive and are very enjoyable overall. The campaign is tremendous and just exemplary in terms of challenge and entertainment. Everyone has heard about the infamous airport mission. If you have not, I will not speak of it. However, the game is just a completely different animal as you progress throughout. One mission I just completed is one of the finest graphical settings I have ever seen and the story is just epic until this point. The campaign may be slightly shorter than what some people had expected but this does not make it bad. It could be that the game is so good that you just want more, regardless of how long it is. You then take into account that the game has 60 special ops missions on top of that that have to be completed on multiple difficulties make this game not only very lengthy but also extremely worth the money that you will pay for it.
The difficulties of the game have been redone and are now impressively set at reasonable levels. I am a veteran of the series and also play on veteran in every game that I have played in the series. I have completed Call fo Duty 2, 3 and all but one mission of 4 on veteran and have been hugely challenged in each, almost to the point that I did not enjoy it. MW2 is completely different in the fact that it uses the difficulty settings well and will suggest to you that you need to go up and down difficulties as you play. Amazingly, veteran is not that much of a challenge compared to the last Modern Warfare game and will actually give you a reasonable chance to recover if you are hurt in battle. Also, in this one, there is no real volleys of grenades that will consistently kill you. I hated that in the last game because it made the game very frustrating and took away from the actual enjoyment of the game.
The last thing I want to cover is the multiplayer. I must admit that I have come to hate the multiplayer in Call of Duty Modern Warfare 1 but this is an entirely different kettle of fish. I haven't found any glitches in the system so far and cheating has been non-existent over the time I have played it. The ranking system returns but the prestiges are much harder and are more expansive. With more maps and more guns than ever before, I have really come to enjoy the new challenge of MW2.
Bad points:
I am trying my best to write an unbiased review but I am finding it very hard to do. The only bad part of this game, are not even that bad. The first of which is the difficulty level. I know I have listed this as a good point too but I feel that for players like me, who have played the games from the very beginning like something a bit more of a challenge. That being said, I didn't get too stuck on any level and accomplished them whenever I gave it a few tries. For new players the difficulty levels are a plus but I felt it was a bit easy. The second thing that bugged me was the length of the campaign. You may or may not be right, Lee in the view that it is too short and I feel that more should have been added. This may or may not be because of the fact that I wanted more to play to be honest.
Anyway, this game is fantastic. It is a must for anyone who owns a console it is available and I am sure that it will hit at least 20 million copies sold. It is nothing more than it deserves to be honest.
