A Halo title should be higher on the list. I didn't go through much of the list but it should be close to the top 10 or in the top 10. Why? Because it's pretty much a definitive title in the genre for consoles and is a landmark title in that area. Similar to Half-Life. In fact I'd put Half-Life higher than its sequel and close to the top too because it's one of the earliest examples of an FPS game that's cinematic and well-scripted.
For the same reasons as above, World of Warcraft belongs in the top 10. It's a genre defining game and has set the bar and pretty much nudged it up multiple times since its release.
Uncharted 2 again can probably be described as a definitive title but it's easy to pick apart why I wouldn't put it so high. It's incredibly linear and has too many sequences in which it's barely gameplay (ie being forced to walk through cooridors while a character talks to you). It's also a fairly short game and the multiplayer is far from great.
