That was a pretty ignorant statement. Unless you understand the inner working of game design, I wouldn't recommend writing it off as easy.

In fact, it is my understanding that making DLC is actaully much harder, because they have to consider everything in the original game with which the DLC comes into contact. They have a lot of constraints to consider; DLC isn't a "smaller, less complex game".
