Unlike most American sites and magazines, Edge use the full 10 point scale. 7/10 for Killzone is a good score. Arguing with review scores in general is really annoying as they are just opinions. Have any of you even read the issue? I doubt it as I'm a subscriber and haven't even received it yet.
In Preston, UK, nowhere has it in stock. In Game they are on shelves with "coming soon" stickers (meaning out of stock) and in GameStation it says "back in stock soon" on the boxes. Maybe it was undersupplied.
