Finally finished it. Did all the things needed to get Excalibur/odins spear/mjolnir, got all the abilities, got all the viewpoints, pacified every region and finished the main story and the asgard/jotunheim stories. Also did all the anomalies to get the secret ending.
Took 99 hours and 57 minutes... fecking exhausting game. It's great in large parts of it, but seriously needs to be cut down by 30 hours or so. Just drags on and on. I didn't go full completionist and didn't both getting a lot of chests or whatever, but did maybe a little over normal playing pace. Normal playing pace would probably take 85-90 hours to finish. Just way too long.
