NOLF 2 is an awesome game. You play throught the single player missions and get a great story...but then you play through the co-op missions and get a side story that fills all the gaps. The best way to describe it would have to be using MiB. Agents Kay and Jay go in, see an alien, make a mess. That's the story you get in the single player. But then the cleaning crew comes and takes care of everything else. That's the co-op story.
Now that I'm done with horrible analogies, I will say that choosing between this and Generals may be tough. Generals looks awesome, too.
By the way, if anyone can come up with a better analogy, please, feel free to let me know. I know mine is horrible.
