suprise suprise halo 3 and call of duty 4

i'm suprised nobody has posted about these 2 games! these are currently the best multiplayer games on the 360 i think. what are your opinions?

I play both, COD4 is growing on me, but I'm still too busy playing GTA IV.

I moved a bunch of topics in here just now so you'll see the halo 3 thread, where people also talk about cod4.
