Cod4, I play it everyday.
CoD 4. Is there any doubt? Let's see, shoot aliens or one of the most realistic real life combat games ever.
I voted Halo 3, but I still love COD 4.
I find Halo maps to be very easy to navigate, and is a very easy to learn game. COD4 is easy to navigate, nonetheless, but Halo takes the cake there.
Halo is a lot more peppy and futuristic. COD is about destruction and emphisizing that it's all out war. I like the cleaner design in Halo.
Another thing is the fact that COD's maps are sized much larger than Halo maps, making small games longer and more frustrating.
That's basically why i chose Halo over COD4. I still like COD4, but I like Halo better.
I gotta go with halo 3 on this one.
Halo is rubbish, can't stand it. I prefer realistic games, Call of Duty being my favourite. World at War is preferred to Modern Warfare.
I'd have to go for Call of Duty 4 Modern Warfare all the way.
