70 hours according to Steam. Veteran difficulty. I didn't hit the level cap interestingly, only managed level 19, but could have easily gone to Ukaizo several levels earlier. The faction quests and interplay in Neketaka were probably the better parts of the game for me; especially the atmosphere and writing in the Gullet and some of the early quests there. I didn't particularly enjoy the main quest that much unfortunately, nor too many of the new companions. I missed the likes of Durance and Grieving Mother for sure!
I won't be touching the game again until all of the tweaking is done on Path of the Damned and all of the DLC are out. Make it hard, Obsidian!
