I spent around three months doing it thoroughly, I didn't even touch Story Mode, which is big. This game is big.I already expected that... 922 pages of comments for sure there's a lot of content in this game already, i just wanted to know how many hours to plan my queue since i dont have a lot of free time nowdays
But in fact to beat the boss and get the victory screen you can play for around five hours, I think, if you read people's guides on combat and progression beforehand. You can go from the starting to the final location this way and call yourself success. But there are around 30 characters with branching scenes and some more cool activities. This game is a damn monument of porn archetypes for the past 10 years I guess.
