Over 100 hours of gameplay.
Became the most comfy video game I've experienced in my my whole life. Easily my second favorite video game of all time just behind Utawarerumono Futari no Hakuoro. Storywise, it's magnifique, got tears in my eyes. For the gameplay, sure it's a grindfest, especially when you reach the 2nd half of the game, but surprisingly I can't get mad at it. I don't know if it's because this is the first NIS game I've played, but I don't thing that's the reason.
This is truly a great dungeon crawler game.
