The game is good, a bit short like most current games, but fun. I feel that bringing it upto date has lost some of the CoD magic, but it is a good game.
There are a good range of missions, and some fun achievements, but they are weighted a bit to much to the Veteran campaign, and there are no MP achievements.
The problem comes with the Collectors edition, it is bascially a card box, which contains the standard retail game, a book, a DVD that looks like it fell out of a Newspaper, and a poster.
If you are expecting a metal tin like me you will be disappointed, but if you want the kudos of having the Collectors edition £44.99 is a reasonable price, and the game is defo worth a purchase.
