Black Ops is going to be the most popular game on YouTube when it comes out (in November). I suggest you look into that and check some well known MW2 youtubers while you're at it (to see what they do to get views).
A few examples of popular MW2 youtubers: Hutch, Seananners, Tejbz, Wingsofredemption, TheMoodieSwede.
But I guess if you're not into COD those won't matter.
