I must be a really good COD fan(except when it comes to paying them the money "they" want).
Loved COD 2, that's when the developers saw the potential of this series.
Enjoyed/Loved Mw1 allot, more then enough as so everybody else did
I Loved COD:WaW also, It was a revamped version of COD2 in there current engine in my opinion. (I mean whats better then getting bolt action kar98 kills out in the distance, 1 bolt chamber rape.)
I Disliked Mw2, maybe I foresaw the horror of replication and lack of "ingenuity" in there new developments(aside from no Dedicated servers).
I Liked(not loved) Black Ops, I was playing(ps3 massive crowds)online and having a blast with Sticks n stone's, there mini game's, and cooked quad kill grenades on villa!
I am Hating MW3 right now, why? The intro video's for MP are absolutely outstandingly similar to everything back to MW1... Run n Gun again. It's like a revamped Combat Arm's, New Weps are the only thing that should draw peoples interest(once again)(sarcasm).
I could care less about the story, because honestly.... There was no real vain or true emotion felt for the COD:story line. It is not the same as Halo, and also Gears of war. People cry'ed and were addicted to the story line of those games.
but...... For a Story line on COD, it was more based on "Wow dude check out the action packed campaign!!!"
Personally the only true Ideal reason I see why people are going to play MW3 is because, its based on Run n Gun, which in my Total opinion is about as addicted and self natural as FACEBOOK... or drinking a cup of coffee. People(even I) have gotten used to it like an addicted arcade game pass time. It is not about the development and breakthrough's at all.
COD has turned into an everyday pass-time because of its popularity, and has seem to hit a part of everybody's brain where the tactics (run n gun) are pretty much as popular as Tetris/ or any alike game. It's a access like water/food/shelter/music/comfort where people necessarily never want that to stop, and its understandable.
They get there sales, because most of all, young adolescents are the most "ambitious" when it comes to this, and they also have the most free-time to use COD like tetris in a similar manner.
That's what I have noticed.
