I have not played the Gears Of War game, but I still found this to be funny. I can see why some people are a tad mad at you about this. It's just that in terms of what makes a good game, I honestly don't think character development should be that big a deal. It's a game, not a movie. Of course, movies based on video games are mostly bad anyway. The animation was as fantastic as ever.
I do think that it's less confusing when you name something Gears Of War plus the number. I like how the voice is so gruff and stupid sounding in this. I should have expected there to be a penis of some kind involved in this. Not that you're known for it, we're all known for it! This is the Internet, after all.
