really?.....i think i'd feel like i'm missing something.
I own it. I don't play it. It is just an arena that you have to fight off wave after wave of level 51 bad guys. There is nothing to miss there. No XP, no loot, no nothing.
Check out the reviews on Metacritic:

Unless you have a core group of three other friends and all of you have maxed out level 50 characters, I wouldn't recommend Borderlands: Mad Moxxi's Underdome Riot to you. It isn't balanced properly and, since there is no normal XP awards or loot drops, you won't find your character improving as your struggle through the endless waves.
