Story


"What is real is defined by what is not.
Who one is defined by who one isn't."
To move forward, one must accept these truths.
"Yes, in this prison—this cradle—
my dreams and reality became one."

Renowned adventurer Adol “the Red” Christin and his companion Dogi arrive at Balduq, a city annexed by the Romun Empire, only for Adol to be detained before setting foot inside. While imprisoned, he meets a mysterious woman named Aprilis who turns him into a Monstrum, a being with supernatural Gifts and the power to exorcise monsters. Now, Adol must ally with his fellow Monstrum to fend off the fearsome threats emerging from a shadowy dimension called the Grimwald Nox, as well as unravel the mysteries of the Monstrum curse, and the truth behind the unrest within Balduq.

✦ AI summary

Ys IX: Monstrum Nox is praised by series fans for its addictive action gameplay, excellent soundtrack, tight controls, and beautiful visuals, with most players finding it comparable to or better than Ys VIII. Common complaints include companion AI getting stuck during exploration, some recycled mechanics from the previous game, and slightly outdated graphics for a 2019 title. Players familiar with the Ys series and comfortable with anime storytelling recommend it as a worthwhile purchase.

Good and fun game. If you are coming from YS 8 you will be right at home. Unfortunately, raids are back, with different name but similar format, lots of mechanics from 8 are back actually. The new part is that you and your characters have like a superhero secret identity with special powers. Story wise, very anime as usual, but it a good way I guess, world ending event that you have to fight. Slightly shorter than 8 I think. What I didn't like is how buggy your companions become while exploring, they keep getting stuck trying to climb up a wall, or keep jumping into a cliff. Visually might feel outdated considering this game came out on 2019, but that is a personal take, Totally recommended IF you like anime cliches, you don't mind visuals AND, of course, you like ARPGs.

Unpopular opinion but I think this game is slightly better than Ys VIII, better supporting cast, slightly better combat and raid battles, the story is more character driven and I like that they reference Adol's past adventures. Overall experience: pretty memorable. If you played Ys VIII you will likely enjoy this one aswell.

The Planet Coaster DLC catalogue closed in 2019, so there is no curve left to wait out. Our record shows the collection bundle costs far more than assembling the same packs one by one.
