It's basically a con. Releasing a boxed edition which doesn't work without being connected to Xbox Live, despite developers claiming that it came with the latest patch. Obviously they didn't test it. By the time that I did have connection to Xbox Live in my house which was months and months later I had sold Oblivion along with The Shivering Isles and I last saw them in the bargain bin in the HMV shop that I traded them into. Since then, I have avoided buying Bethesda products for two reasons:
1.) Fallout 3 makes this same mistake as Oblivion and even has the cheek to release three DLC discs (probably which don't work without Xbox Live connection) in one year and then release a package the same year later which contains all DLC + the full game. Other games like Dragon Age have released their DLC in one package along with the game + expansion and don't create £10 disc versions for every DLC they released. So put simply, every Bethesda game always ends up with various other editions and you have to wait for the right edition to come along.
2.) Even with Xbox Live. I still avoid downloading DLC. Call me sentimental but I value holding something in my hands. Say if I was to buy Skyrim near release date hearing that it improves on Oblivion's failures and then hear one year later about DLC on a disc that continues the story or what not, am I to buy it knowing about Bethesda's previous endeavors?
Since 2010, Bethesda have ignored the complaints on their own blog:

I've been simply avoiding their bug filled games such as New Vegas and have even convinced others to avoid them. This sort of service from a company is just unacceptable. To release a game that doesn't even work and then offer hardly no support for it, that should be illegal.
