When you get around to playing New Vegas make sure you have Old World Blues installed too. I don't usually care for DLC, but it's amazing. It's basically an entire storyline based around mad science, which... Well, it's amazing. You get kidnapped by a bunch of brains in jars, fight a giant robot scorpion and have to fight off the evil machinations of a supervillain that also happens to be a toaster. ...Really, it is so awesome. ^_^
