In response to Tequila Shot:
Yeah, he had fun. Perhaps it's because he realizes that it's a game and that dying in it isn't a big deal, and that the fun come from occasionally making others die.
Your rhetoric isn't apt. While it's true that experienced players will generally own the inexperienced ones, the game is set up so that it's NOT an impossible task to actually kill a level 70. Me and my friend would have 0.000001% chance of even scoring against an NBA player in basketball, so that assertion is a hyperbole, and doesn't logically prove anything.
Next, did you ever play Wipeout? Or any racing game for that matter. You had to learn the track, it's part of the game. Mastering a game is part of the game and when done well can make the game enjoyable.
Yes, it is hard initially and then you get better at it, but of course it is, that's axiomatic. Do you get completely slaughtered moments after spawing over and over again? No (at least not on 360). At first you run around for a bit, die, watch the kill cam and go "Oh, that's how that works, guess I won't step out into the open like that again"... lesson learned. Then you think, "maybe I should trail behind this level 55 on my team and watch him and help him out"... another lesson learned. All without a tutorial mode to lead you by the nose as to how to do well in a multiplayer match.
The big question is, is it worth the "burn in" phase. And for MW2 I think the answer is yes. It's enjoyable even while being owned, and then when you can get to the point where your owning left and right with knife kills, you feel like a badass.
It's not like I'm a fan of "Hardcore" games (a la "Fester's Quest", where when you die and start all over), but having a mildly interactive (crappy) movie isn't much fun either. Gaming should be challenging and fun at that same time. That's why people talk about the difficulty curve for games. For Yahtzee to not even sample that curve is a dereliction (sp?) of duty. He really should have at least TRIED (what many consider) the best part of the game.
Finally, since when is dying in a multiplayer game akin to being a fool? A fool is someone who places too much value on whether they die in video games.
