You should have acted. They're already here. The Elder Scrolls told of their return. Their defeat was merely delay until the time after Oblivion opened, when the sons of Skyrim would spill their own blood. But... there is one they fear. In their tongue he is Dovahkiin; Dragon Born!
Some may claim I'm trolling, but I'm not. I seriously didn't find much entertainment value in Skyrim, and I'm glad that I was playing it on loan rather than having actually bought it. It's Oblivion with a new coat of paint and some better conversation bits. It still doesn't have much of a main story, and the sword play is still questionable at best (Kotaku's one writer said the same thing a few weeks ago).
I could go on -- but I think this'll probably get voted down anyway so what's the point?
Also, thanks to the three people who actually agreed.
