Bethesda has opted to use Fallout 3's model instead, which has you face "harder things" as we level up, but "easier things stay around" for us to "just decimate".
The progression system in Skyrim has been redone since Oblivion's days to make sure we feel powerful as we slay dragons. In fact it's "a lot more like Fallout 3, where as you level up you are going to see harder things, but the easier things stay around as well."
Combat will be no walk in the park assures Todd Howard, but we'll face new and unique enemies to avoid repetition and keep it exciting. "You’ll still run into the weaker stuff and you’ll just decimate it,” said Bethesda's Howard.
Another change is the conversation system. "There’s very few completely random conversations,” added Howard. “We’ve gone more towards a system, like we did in Fallout 3, where they have a specific conversation with a specific person about various topics.”
They also took a lot of lessons from Fallout 3's impact of environment. "We realised in Fallout 3 that that kind of environmental storytelling, where you come upon a little scene, is really good,” explained Howard. “And so we’ve tried to do it a lot more.”
He teases that "just about" every dungeon has something unique. The Elder Scrolls V: Skyrim releases on Xbox 360, PS3 and PC November 11th.
