I tried COD4, COD world at war, and COD MW2. They were all the same with different tweaks and settings. I learned my lesson already. The COD franchise owners would love me to be stupid enough to keep paying $60 for the same game, I'm sure. So no, I won't be "trying" this game for a fourth time.
Also, if you are willing to give me the $60 required to "try" this game, then I will be glad to "try" it for you and give you my brand new, shiny opinion.
You can say the same thing about BF4, BF3, BF: BC2, BF2142, and BF2.
They're all just different maps, different weapons, different game modes, and a few gimmicks thrown in the mix here and there. BF2142 - we have MECHS instead of tanks, ZOMG! BF3 - now you can blow up the walls of buildings... for no apparent reason! BF4 - now you can blow up EVEN MORE stuff, and some buildings will COMPLETELY collapse!
With the exception of the rare occasion when someone is hiding behind a destructible wall and you just happen to have an RPG, it's all a gimmick. Why I'm completely safe inside a shipping container, but not inside of a concrete building? The shipping container wasn't programmed to be destructible, that's why. Don't get me wrong, I think Frostbyte is a step in the right direction, but until we get to the point where entire maps can be leveled like they would be in real life with so many munitions flying around, it's only a minor part of the overall game. If they get to the point where every structure can be damaged and collapse in a realistic way, and build a game mode where one team actually needs to prevent a building / area from being destroyed, being mindful to important structural assets that the building relies on, it will be a game changer. Until then, it's kind of fun to look at, but little else.
I absolutely love the Battlefield games, and am still playing BF4 somewhat regularly. Saying that they're so evolutionary compared to the COD games is a farce, though. Both lines are just recycled concepts with some new frills and little truly new. And you know what? They're great fun, too. Don't buy these games and complain about how much it's like the last one; buy these games knowing that you're getting the same thing with a few artistic flares, forget the nay-sayers, and have fun.
