as someone who played 25 days on cod 5 before recently switching back to cod 4, i have to say that cod 4 is just all around a more well done and fun game to play. besides, cod 5 is basically just cod 4 in the ww2 time period, there was absolutely nothing new about it that set it apart from cod 4. when cod 4 came out, it was a totally new experience. as we can see from all the articles and videos of mw2, it is a completely redesigned game that brings us some variety we havent seen in 2 years. all i can say is that my expectations are that mw2 will blow away both cod 4 and 5.
