"Like the HL 2 review that talked about Halo the whole time"
Tsk. If you're going to nitpick (which is your god-given right as someone with an Internet connection, of course), at least try not to be myopic about it. The HL2 review had a single paragraph saying HL2's vehicles sucked in comparison to Halo 2's and was immediately preceded by a sentence saying Halo 2's AI was a bit better. Stick the review in a centrifuge and you're going to get about 3% Halo comparison by volume. 4% if you count the indirect bit where I said HL2 was the best solo FPS of the year.
