I don't really understand where you're coming from with this Circumstantial Ad Hominem because I was never trying to assert that your claims were wrong or right in the first place, or that you're doing it out of self interest, merely that it is pointless to listen to you because you're admittedly biased.
edit: it also seems to me you're completely ignoring the fact that it's not a "100 greatest games ever" but some weird shiet "top 100 games we'd like to play right now" list. And seeing that as recently as April 13th Halo 3 was the most played game on XBL according to the weekly ratings, despite being one of the oldest games on the console, it'd seem a vast majority of people are thinking the exact same thing. So I can't exactly see why it doesn't deserve it's place in this specific list. People like to play it. That's all this is about.
