That was a saga indeed!
I loved post-credits how it panned back over the landscape, showing windfarms ... pinning it back to the present.
144 hours and the main questline was maybe only 2/3 of the content of the main game. Killing off the remainder of The Order was a lot of fun, there's Tombs, finding all the Bureaus, Contracts, Hunting, Fishing (that was a faff, actually) ... then the River Raids, which have me a decent insight into the two DLCs, Wrath of the Druids & Siege of Paris which I will no doubt buy in due course but I'm a bit exhausted with it for now.
I didn't get into Dawn of Ragnarok (included in my edition) because after just playing God of War: Ragnarok, I'm a bit overdone on the Viking mythology (and there "dreams" in Valhalla that take you into the same universe). Maybe later.
Thoroughly enjoyed!
The Isle of Skye side-quest introduced me to Kassandra (from Odyssey) ... so, probably play that next.
