@zoner: Most people expect online multiplayer these days though. While it's acceptable for the Wii to not have it, I think most would expect a sports title to have it at launch on the high-def consoles.
You need to join a clan. I just posted a review of MAG and that was one of my big criteria in recommending this game to people. You have to be in a clan and use a mic. The experience is just not fun without being with friends. And yeah, people can be jerks online. Internet+Anonymity=Dick.
If you guys are still doing these bombing runs, add me, please. I usually run with people from Neogaf but always prefer playing with people in a party if possible and the more the merrier as far as I'm concerned. Haven't been as many of them on MW2, most are on Uncharted 2.
