Only things really worthwhile in Dead Money was the Assassin Suit, all the Pre-War Money from turning in Sierra Madre Chips, and maybe the Police Pistol. But even those don't make up for the $10.
Actually, this whole game seems like a waste of money and time because you can't do stuff without having one of your quests bug-out(POST PATCH), your damn gun move above or below your view in first-person, and the fact that I gotta put the final battle on hold so I can go do some dumb sidequests, like finding a love robot. To initiate the final quest with the NCR in New Vegas you gotta talk to Colonel Moore. A little pop-up appears and says something like "you've commited yourself to fighting with the NCR agianst the Legion this is the point of no return before the game concludes." What the forget am I supposed to do now, tell Moore I gotta pause this giant-ass battle so I can go do some errands? "They're attacking Vegas! You must help-" Yo Moore, I'm really happy for you, I'm 'a let you finish, but Freeside has the best Side Quests of all time!
And don't take this as one of those "I hate Fallout 3 and New Vegas 'cause they new school" arguments, please. I really would like this game if it weren't so damn messed up.
