I have to admit, after reading the books avidly (and loving them) it seems that Karen Traviss is best suited to literature as the campaign lacked something in the story that was there in Gears and definitely in Gears 2. Although happy with the story I didn't find myself drawn in like previous Gears games.
Perhaps a second run through will change my mind. I was impressed with parts of the story, but sometimes wonder if the desperate need to 'add more colour' (which was never an issue for me) caused them to try and squeeze in all the different locales which stopped the thing picking up some speed before it had to get moved along.
The Easter eggs are pretty sweet too. Example
Spoiler ->Playing a round on multiplayer Gridlock without having any ash people disturbed gets you a poignant tune on the second round
