This is the issue: why do we enjoy the games that we enjoy?
I submit that competitiveness has traditionally been an aspect. Pulling back and taking a panoramic view, I'm not sure I want to live in a place where people have fun by just participating. I'm sure you and I could sprawl this discussion into something that wouldn't be interesting to most, but my thoughts are obviously rooted in my feelings regarding Objectivism and man's nature.
But to scale it down to VG board relevance, it ain't just me who is worried about this game. Other forums are filled with COD veterans who are worried about these new additions. Even the perks have perks -- there is something called "pro perks" that make the perks even that much perkier. It's getting ridiculous, and players are worried that MW2 will be a noobfest. I find that ironic, because I've always considered COD multiplayer to be a noobfest.
