It was an alright length for an expansion. I was entertained by it too, but I hate Crytek's storytelling "skills". Those cutscenes that were meant to be "emotional" seemed laughable for me.
Well at least with Crysis better job than with Far Cry was done, especially in voice acting department.
EDIT: One more thought. Did anyone else found it funny that Crytek seemingly didn't want to make themselves look like idiots by locking highest settings only to be available in Vista this time around, but changed names of settings, like Enthusiast, Gamer, Mainstream? Those are the most terrible names for settings I have ever seen too.
