Final Fantasy XV’s story mode will have around 40-50 hours of gameplay.
At the end of Square Enix’s E3 live stream yesterday, FFXV director Hajime Tabata answered a number of fan questions, one of which related to the game’s length.
"In terms of clearing the main story, we’re anticipating about 40-50 hours of gameplay," said Tabata. "At the very least there will be 40 hours of content to enjoy. But there are a lot of side quests and other extra things. With just the extra stuff alone, we’re looking at maybe 100 hours of gameplay. So if you count all of that, maybe we’re looking at around 200 hours of gameplay."
