Both of these games are specal in thier own way and comparing them is next to stupid. Call of duty three has exceptionally higher graphical detail, amazing physics, yet it is not as creative as halo 3. Each game has its ups and downs.
On another note, the online play differs substantially, in Call of Duty 4: Modern Warfare, multiplayer is close packed and you are in a constant firefight, it is highly realistic and you can only live a few shots (which i love to bits). on halo 3, you have quiet gaps, and you are not constantly fighting, yet the battle is more creative as in you can use vehichles. in Call of Duty 4: Modern Warfare i am very skilled at multiplayer. I am capable of actually surprising a person with a shotgun by charging and knifing them... good times... good times...
Halo is noob friendly ie you cna get hit 3000 times and not die CoD you get owned in a couple of shots
Oersonally CoD But If I could I would play both as they are different I was gonna get an xbox for just Halo 3 and ps3 for everything else but couldn't afford both.
Also everyone at school has an xbox so I can't play CoD with them because I have a ps3 but ye they are both different I like the perks system in CoD though most people here are just fanboys who havn't actually played both games like the people saying Halo has better graphics
why dose everyone talk about "halo 3 or call of duty 4" ???????? i think call of duty4 is but .... stop talkin about halo 3 and call of duty 4!!! this is the 5th one yet!
