ugh...I don't have a problem with you saying what you did in the video Bob. But, I've gotta say I think you're reading WAY too much into it. The Covenant are, as you said, a group of aliens who have basically been forced to serve in a slave army. But more importantly they've all been mislead and deluded by the overlords (the "prophets")for selfish gains.
The regular gamer, I believe, sees this quite clearly. Bungie seems to have made it a point to show that the prophets are the real bad guys, as well as some of the misguided zealotry that some of the members of the covenant have. If anything the average gamer will just see them as the bad guys (regardless of the fact that they're a multi-culti army with arcane beliefs.
I also take offense to many of the people saying that NOBODY plays Halo for the story or subtext. The original Halo was perhaps one of the most memorable and enjoyable experiences I've ever had with video games. I respect you're right to disagree, but that doesn't change the fact that there is a ton of story going on, especially if you read the books and such like I have (I'm not saying that YOU have to or should, I'm just saying that there is a lot more here than many people give it credit for)
Further more, I find some of what you said a little discouraging in light of the current world climate and attitude. It seems to me that too many people are taking the idea that there "are two sides to every story" a little too far. I'm all for cynicism and understanding that not everything is black and white, but for God's sake, the alien race in question is trying to exterminate the human race! I don't know about you, but I'm pretty sure that makes them the bad guys no matter what color their skin is, what religion they adhere too, or what kind of agenda they have.
I'm not advocating simplifying things down to the way they were before the World War I and World War II, but it's important to look at things realistically (even if it's just a game, because how we feel about a game, reflects our real world thoughts and views). This should prove to be a good weekly column though, regardless of the subject being discussed.
