So I was reading all the reviews that said it took anywhere between 50 and 120 hours to beat the game depending on how many side quests you did. I am currently at 31 hours and honestly have no clue how much of the main story is left but it doesn't feel like a whole lot. My brother also played the game and said he beat it at 30 hours which caught me off guard. So is this 100 hours game time an overestimate?
