Skyrim is such a damned good game, been playing it since 11/11/11 (mods have helped keep it entertaining, but still, even alone, the game is awesome.)
A few months ago I found a location called southfringe sanctum, that I had somehow missed for years, it even had a short quest inside.
And now yesterday, just when I thought I had seen all locations I get a quest from the solitude executioner (who for some reason I've never talked to), and he tells me to go to a place called ironback hideout. I was like... wait, that doesn't sound familiar. It wasn't a cave, or some epic location, but still I was so surprised to find something new, and just another moment where I've thought.. "damn this is such a detailed and awesome game." The fact that I can't deny there are still things I haven't done in this game just makes me love it even more.
l would totally sacrifice a goat in honor of skyrim.
