Which one do you prefer?Which is more fun for you?

Online Co-Op 

+full screen

+great with headset

-need to purchase headset

-possible lag

Offline Split Screen

+perfect connection

+no headset needed

-Split screen

-need friends/extra controller

I prefer online co-op, i hate split screen, i have plenty of friends, but i rather play with them online with a headset.

What about local system link co-op?

Online is a great addition, but it should always be 'in addition to' local play, not 'instead of'.

Being in the same room with a friend and seeing them have fun>>>>being somewhere else and assuming they're having fun.

split screen all the way !

You also missed the possibly best part of split screen. Having a friend beside you, drinking some beers together etc. much better than talking via headset.

System link.......OT I have to go with Split Screen cause you and your friend are in the same room. My TV is a '52, so screen size aint that bad. On a smaller screen online is the way to go.

AGREED

That's even better than split screen.

I prefer Split Screen. Nothing beats two or more people in the same room playing the same game.

i want both, otherwise don't bother charging me full price

split screen, action is more fun in person

I myself like playing local system link with two people on each T.V
