When Skyrim and Steam teamed up, we had a feeling whatever they created would be an instant, smash hit, and it looks like we were right. More than 2 million mods have been downloaded from Steam's Skyrim Workshop, and players have published more than 2,500 mods since its launch on February 2, Bethesda says. Mods range from Valve's own Fall of the Space Core, to graphics updates, varied weapons options, mechanics changes and posh mudcrabs, as seen in the "best of" video above.

Skyrim outsold all Steam games three-to-one in its first month, and it outsold all exclusive titles for both PS3 and Xbox 360, Bethesda claims. The average Steam user has played Skyrim for more than 75 hours, which is a ridiculously high average. Modern Warfare 3 outsold Skyrim for the year, but Skyrim was the second-most-successful title of 2011, beating other blockbusters such as EA's Battlefiled 3. And it doesn't even have multiplayer!
