He did say Skyrim's story was "mediocre," and honestly I think that's being generous as far as the main quest goes.

It kind of sucks for Skyrim because the story is also extremely setpiece oriented, but setpieces need to either be very mechanically good (so nearly none in Skyrim) or tie into something that makes them feel good (so nearly none in Skyrim) and otherwise it feels like being locked into an amusement park ride.
