I often don't have enough space to go into every element of a game in the blog posts. It just doesn't make sense to throw more than 1200 words or so at a person in that format. It's a get in there, get the idea across, and end with flourish kind of setup. So I decided to narrow this critique down and just focus on the most interesting part of the game.
On a lot of levels this is how the process is sustained best, ignoring the faults and just talking about the interesting parts of the game. In COD 4' case, the three passive sequences and how they are exercises in amusement park ride design. The rest of the game is fine, you play an especially badass marine/SAS soldier and the game design reflects it.
These moments however, are quite interesting.
