COD is always the same, and basically everybody has grown tired of it. And 6GBs of RAM for Ghosts.. Pfft
Older COD games used to be a lot simpler and fun, because there weren't a HELL-OF-A-LOT features. I literally took like 20 minutes deciding on what perk(s) should I use..
Meh
I left COD long ago, when I used to play COD4 and MW3, I got so good in COD4 to the point like everybody would call me a hacker. That is why I left it.
And mainly because of the childish community.
