Looking back there are 2 games that really legitimized DLC as more then a cash grab, at least for me. The first was Fallout 3, which through the power of INTERNET changed the ending and added hours of new content to an already robust game. The second was Borderlands, which in true Borderlands fashion Used DLC to continue the main plot not once, but TWICE! Suck it Bethesda!"
I'm partial to the mass effect 2 DLC where more story was given within the main quest line. However it is only good if given before you beat the game.
