I am the big fan of call of duty 4. It is my favourite game. So I always go for it to play online. There are superb animation and good sound quality in it. I like this game very much.
This is the main thing about it. I've played the demo loads of times. The press conferences are really good as they can get really heated if your team is under performing and I've noticed that they can make a real difference to your teams morale. I like it very much.
It is the great game ever. I do love 30-odd mins everyday online playing CoD4. Very addictive, and one of few online shooters that really rewards using your brain, and not just running around like a headless chicken shooting at everything. That's why I like to play this game.
