In the latest episode of PlayStation Network’s Qore (via VG247), host Veronica Belmont confirmed that the game will last at least ten hours.
“At the start of the game, you wake up a mystery. And for at least the first ten hours or so, you remain a mystery,” Belmont confirmed.
That’s not to say the entire game is ten hours, as we well know the first was much longer (I logged around 19 hours), but at least we have something. Remember, she says “the first ten hours.”
