I like when kids who are like 13 bitch about little kids on games, and how mature and different from they're age group they are. When I was that young I thought the same stuff, I now know I was wrong. I don't care about kids playing the game, I still have fun. I just mute it if someone is annoying.
CoD isn't a great game but it's still pretty fun. It's probably one of my favorite fps games to play. I enjoy playing it casually online especially with friends. It's fast paced and you can play with random people on the internet no problem. But overall it's nothing amazing, just decent.
