The main thing that bugs me about these reviews is that, although they reference the other Civ games, their tones imply that this is the first time Civ has ever appeared. I realize that someone who's never heard of Civ is reading the reviews, but they don't do that for Halo.
"Halo: Reach is a game where the player shoots aliens in order to advance the storyline."
See what I mean? You'd never see this in Halo reviews, yet such phrasing happens all the time in Civ reviews. It's just weird.
