So, is there a game out there that captures the same vibe as Skyrim?

I know the Morrowind and Oblivion fans will jump in immediately to name those titles, and that's valid but I'm looking for titles less removed from the Elder Scrolls franchise.

I just want to play a game in a fantasy setting that's sort of a sandbox for your own questlines and activities. The Witcher games are great, but as open world as the game are, they also feel a bit linear in their progression. The nice thing about Skyrim is that you can literally plop yourself anywhere on the map and go about your adventure. Certainly, that's helped by mods, but I was wondering if any other games came close.
