I personally think it's a pretty darn cool intro, although I see Rand's point.
To a casual games gamer, you are going to sound elitist. Especially since you're the one who brought the word up! This might irritate Peggle fans briefly... but they'll appreciate that Peggle was so mighty as to make you see things in a new light. Especially since you demonstrate self-awareness of your elitism.
People who are big fans of Modern Warfare 2 probably won't take too kindly to it, and there's no redeeming revelation for those people (since they probably thumb their noses at stuff like Peggle, too). The intro will likely turn these people off right away. It's up to you whether or not you're okay with that. It's not inherently bad to turn people away.
To a fellow elitist like me, who also likes to do my own thing all the time, your opening paragraph has created an atmosphere of inclusion. Right away, I identify with you. I mean, the alternative is identifying with the unwashed masses... and who wants to do that?
So yes, it's a divisive opening that will have a variety of effects on a lot of different people. That's not a bad thing. Anyone who reads your review knows where you're coming from. And you want to share your experience with people like you. I thought it was a good experiment, and effectively written.
I would actually say the gameplay bits are the ones that start to drag. The problem with really super-cool puzzle/casual games is that when you describe the gameplay in writing, they almost always sound a lot less cool to the world. I have a clear idea of how the game plays, but that doesn't make me want to actually go and play it. My general suggestion for these kinds of "this one is cool, REALLY" reviews is to focus on the experience, or the high-level view of how the game engages the mind, or perhaps your feelings during a particular moment (and you can often work some gameplay description into such examples).
This is advice that I almost never follow myself. We all feel some kind of compulsion to describe gameplay. It's a hard habit to break -- the world has indoctrinated us that "reviews need to describe game mechanics" -- but I think it's a habit we need to break if we're all to grow as critics.
That being said, I thought the bit about twitch reactions not helping was excellent as it focuses more on who will like it and why, and less on the details of how the game plays.
