Whats Better Call of Duty 4 Modern Warfare or CoD World at War?

I personaly think CoD world at War is better only beacause i like the guns and Cod4 got kind of old. Thats only my opinion so yea im just asking for yours???Whats Better Call of Duty 4 Modern Warfare or CoD World at War?
Cod 5 Is way better you can kill zombies how ever long you want you will die. cod4 is more modern and has m16 m4 Ak 47. Cod5 vehicles cod4 no vehicles. But you can ride in them.Whats Better Call of Duty 4 Modern Warfare or CoD World at War?
I agree with you, I think after playing COD4 for a year the new guns and maps are a nice change of pace. I don't see why everyone is complaining about it being in WWII again. The guns are not any worse than the ones in modern warefare and now we have dogs, tanks, and flamethrowers. Bouncing bettys are way better than claymores because you can put them in so many places without them being seen. They are both great games but I think COD WaW is worth it to buy and play.
wat u should do before asking any question is searching up the question in the search bar to see if the question has already been posted, yes it has... ALOT...
