1. Don't know why a lot of Battlefield 3 players are in the forums. If you like Battlefield 3, then go play Battlefield 3. Is the game that boring that you just go to the Modern Warfare 3 forums? (Personally I don't think game is boring at all, I like Battlefield 3)
2. If you don't like the game....then just don't play it! There are plenty of games I don't like, but I don't just go into the forums and rage how I got killed or hated the game.
I came into the forums to actually see what guns people were preferred, what perks they preferred, what they thought of the campaign, what gun perks they preferred, survival mode strategies etc. You know, usual forum stuff. Instead there are just a bunch of grown men complaining on a forum how they hate getting killed over and over, comparing the game to Battlefield 3, and how it is a copy of Modern Warfare 2. Of course it's a copy of Modern Warfare 2 it's a sequel! Changing too much of the game, wouldn't even make it Call of Duty. Battlefield 3 is exactly like Bad Company 2 except the graphics are enhanced, which is apparently all people care about nowadays. Guess no one remembers N64 or Sega. And I don't even know why people think the graphics are so amazing on console. Compared to PC, the graphics on here a joke even with the HD pack. Regardless, both MW3 and BF3 are great games.
If you don't like Modern Warfare 3 that's fine. I'm not going to tell you why you should play the game or anything. Simply send your game back, and go play Battlefield 3 or whatever game you like. Tired of seeing so many rage post in the forums.
