Do share. I've never played CoD so I can't comment. I have however, seen these two comments and comments similar to them far too many times without people actually backing their posts. So do tell us

EDIT: For the sensitive types on the forums, this isn't supposed to be a dike head post. I really am curious as to why people hate the game. People say "I have tons of reasons" then I never see those reasons. Except for the classic "12 year old [censored]" one.
All right then (cracks knuckles) let's do this.
First of all, no matter what people say. The true hate from CoD from most people comes from three things.
1. Activision (Greed, bad business strategy, expensive DLC, etc. More on this in a second)
2. The Fanbase (12 year olds, stoners, failures, and bad mouthers galore. People love to hate on CoD fans almost as much as CoD fans hate everyone.)
3. Popularity (Sheer popularity. Rebelling against what is the most popular. While not always smart, I believe it's justified by the actual game)
Notice the lack of the actual game in this. While some CoD games are indeed terrible, it's not one of the main reasons people hate on it.
First of all let's address number 1. ActivisionThe new EA. Activision is truly evil. Why is this do you ask? Hold on son, I'm figurin to be explainin'.
To understand why Activision is evil we must first understand their business strategy. They find a successful franchise, come out with a new game that declines in quality every year. It sells well at first, sales start to decline. So badly eventually that the series dies and Activision throws it in a waste bucket and looks for the next franchise. They have also been known to kill a series for the sake of the one that's doing well at the moment (True Crime, sorry Antibody).
This is obviously a terrible strategy as opposed to other gaming companies that take 2-4 years to come out with a new, and exciting product.(Even longer for games like L.A. Noire) As opposed to the whole same thing-same thing plan of Activision. They are also known to have ridiculously overpriced DLC packs, and collector's editions. And to typically spend more on marketing than the game itself. All of this greed and hunger for money over good games is what tortures the true gamers who want quality products and not the same lights and smoke show they saw last year. Only this time with an extra firework blast.
Now for number 2. The FansOh how I loathe...no..ABHOR those fans. These are your so called "12 year olds". The bane of the CoD franchise other than Activision itself.
What could be worse than sitting down, trying to enjoy some multiplayer, when suddenly you hear a woman come on the voice chat. She is suddenly bombarded with hatred, requests to make sammiches, and scathing remarks that I can't say on the forum. And us gamers wonder why woman won't have a round of DOOM with us?
The reason for these insults and attacks? The pure immaturity of the CoD fanbase. Unfortunately CoD seems to attract idiots and simpletons (possibly due to its outrageous simplicity). So when you're on a forum, on a youtube video, on CoD multiplayer, or anywhere. You can find the CoD fan, just waiting to announce his pwnage of you to his 6 year old friends. So there's a big reason to hate the CoD franchise altogether for many people, it isn't exactly a shining beacon of intelligence. Not to mention people who play CoD can't seem to play much else. This is the definition of close minded for many.
Number 3. Popularity. Not much to say here, other than humans have a tendency to rebel. So when something is really big and famous? Time for the haters to jump out of the bushes.
MY reasons (other than fans) Which actually includes the games itself. The Games.First of, the Call Of Duty franchise is not what's bad. It's the fans and Activision that's bad. Although there are the recent games which I'm about to get into.
Here are the CoD games that I have played and my anolysis of them
Call Of Duty
Fun game, interesting missions, extremely challenging, etc. I like it! Not as fun as MoH: Frontline though. 4/5
Call Of Duty 2
Same as CoD 1, just better. 4/5
Call Of Duty: World At War
A gritty, realistic version of WWII. Great art and style, a willingness to show the true sickness of the second World War. A sense of uniqueness for a lot of the game occurring in the Pacific. Great engine (remember, I never played CoD 4 so this is like my first taste of that CoD style.), I liked the characters, the graphics were great, the multiplayer was fun, although some disgusting fans, etc. 4/5
Modern Warfare 2
Here's were things get really sloppy. Wait a minute..isn't this the exact same thing I just played last year with some new features and a modern theme? Hmm....
I'm also noticing this is very much like Michael Bay, the game. Explosions, guns, no story, no good characters, fans got even worse on multiplayer, highly overrated, the Activision thing, very cartoony, no sense of grit or realism ala WaW, etc, I hate this game.
2/5
Call Of Duty: Black Ops
One year later... and here I can playing the same thing, just a hell of a lot crappier. The fans are even worse, none of the multiplayer maps are interesting. The guns are boring, killstreaks are terrible, and everyone is so boring cause they just use the Ak-47u
The campaign was even worse, I beat the campaign in one day. It was super short. It had a terrible plot, Veteran was cheap with its respawning characters and grenade spam. The characters were awful and had no development (Mason Woods got best character of the year or something at Spike Awards. The hell? He was nothing but a cliche Vietnam soldier), I could have just watched Full Metal Jacket or Deer Hunter if they really wanted me to see a bunch of cliche Vietnam movie stuff. Explosions, guns, and more explosions make a return to excite the simple minded fools playing the game. There's no tactics whatsoever and it's extremely linear. Enough hating on the game, I didn't even mention the cheap collector's editions, overpriced DLC, insanely big marketing campaign, fact that MW3 will be out this November, so on and so forth.
0/5
Seeing the Activision plan here? They are getting worse and worse. Another point I failed to mention until now is that people are upset that everyone is trying to compete with CoD rather than make something unique. So now not only do you have CoD but you have people who don't have to be CoD trying to be that way. So to put it simple, why would I be playing Call Of Duty when I could be playing Heavy Rain, Fallout 1 + 2, Morrowind, etc?
If you want me to go into further detail on anything let me know.... /rant.
