OOo, bandwagon, let me jump on it........
Why not react if people say the multiplayer is crap when people have used it, rather than assume their system sucks. Isn't it likely you can have a "friends" list and join games with them, infact couldn't you have someone with a great connection "host" a clan match and add specific people.
Meh, who knows COd 4 SP was fanastic with a great story and varied missions, the MP, sucked, it was already arcadey consoley tripe. I was buying COD MW2 for the SP assuming the MP would still be consoley crap.
