Haha, good point.
Of course people should be allowed to post negative comments. Posting a negative comment, and repeatedly slating the game because you have a vendetta against it are a different things though, and it's easily spotted.
Definitely.
I mean, can't you say that the gameplay looks rubbish judging by the videos posted and that the graphics are so outdated, it hurts?
I loved CoD 4 (and still have feelings for it to this day) but playing the same game over and over again works only for CS and a few handful other titles.
