Simply put, anyone who has played the game, and hasn't bought any of the DLC packs, needs this. There's 4 DLC's, at 800 points each (just under 7 I think), so that's almost 28 worth of DLC with this. Plus the game, for this price? Not bad at all. Yeah you have to download them, but do it when you're at work, or overnight.
I have wasted HOURS on this, my kids both LOVE me killing Skags, and the Midgets' laughter STILL makes me jump.
Mad Moxxi is a little lame, but the others (haven't played the Claptrap DLC as yet) are utter masterpieces.
Buy this. Love it.
