If you are trying to strictly rush the main story with zero side quests, no exploration, etc. it will take ~80 hours per playthrough, completionist single playthrough should be over 150 hours. But the game has a vast amount of choice and consequences and permutations, all kinds of endings, etc. All in all 175 hours worth of cutscenes to account for a huge number of player choices. If you want to see even half of that you'll need dozens of playthroughs. So this game will provide thousands of hours worth of content.
