1. How the hell is Killzone 2 overrated? Its campaign is better then most shooters out there and online is great.
2. Why do you have unreleased games like Uncharted 2 and Modern Warfare 2 up there? That's just stupid. Both those games will be awesome.
I think your confusing "overrated" with "overhyped". Because all the games you named were overhyped, few were overrated.
