halo3 vs. cod4?

im deciding between halo3 or cod4 their both good games and most of my friends have them but im just not sure which one is better can you help me?

It ALL comes down to preference. IF you like Sci-fi over realistic, modern combat, then Halo 3. If you like realistic, modern combat over Sci-fi, get COD4. Online, I like Halo 3 far more. It's just more fun and easier to get used to. But as I said, it is all preference.Demonsoul98

this is it. stop posting these threads people!

single player hands down, without question its halo 3 and add local and online coop to that it adds to everything.

and online i take halo 3 because it gets boring way less fast because of more original modes and maps plus forge.

Tough call but I started with cod 4 and I played it a lot and I'm pretty new at Halo 3 so I won't have as much fun with Halo 3 as I did with cod 4 because I liked the perks, unlockables and challenges of cod 4.jeffdoomsday

the achievements on the xbox work as unlockables in halo 3. i liked the perks idea, but i didnt like them in cod4
