Oxenefordscire ended up more like the beginning of the midgame rather than the midpoint of the game itself.
While exploration and combat never changes from that point, the main questlines take a hard turn into railroad central. Early main quests are good at giving you the illusion of choice; later ones not so much. This works on a thematic level (the whole unchangeable fate/destiny thing) but it’s not a lot of fun to experience. Oh, I guess there was one change in the exploration aspects: You’ll want to clear all 10 Anomalies before completing the Norway quest that sends you to the far northeastern point of the map.
Ultimately ended up at 142 hours with 94% completion, all areas cleared, and 65 Mastery points. I never did find any Black Bears or Wolf Fangs for the hunter requests though (or small Sturgeons and big Redfish for the fishing requests), and had to look up the location where to use those various Mysterious Tablets (the area is instantly recognizable, but also easily overlooked since there’s no treasure chests there).
One final thing:
If you’re experiencing random freezes, try installing the “Visual Studio 2015, 2017 and 2019” C++ update. The x64 one fixed the issue for me.
