Despite entreaties from a friend to give it a shot, I’ve been thus far resisting Skyrim’s 100+ hour lure (I only played the previous one through the tutorial; medieval high-fantasy doesn’t inherently interest me; I’m skeptical of the random quest-generation; it lacks the sort of discovery of world-building through exploration that was the main thing I found so compelling about Fallout 3).

That said, here’s a youtube user showing off Valve’s official Skyrim mod adding Portal 2′s Space Core to the game, with some evidence that more is likely to come in that vein (the mod is called “Fall of the Space Core, Vol. 1“), including, discovered through the console, a “Portal 2 quest.”
