If youre a fan of YS series buy it. Its fantastic game though not as great the story compare to ys 8 still its a amazing game with beauitiful graphics and addictive gameplay. Voice acting is top notch. The OST are the best!!! Tight controls and satisfying action And the most important part is Yufa(Raging bull) humongous tits. 10/10 LESSGOOOOOOO YS

My second YS game coming straight from 8 and it's definitely more YS fun! Big city with lots to collect and do but not overwhelming amounts of collect-a-thon. Really, just right. I definitely enjoyed this about the same as 8, both fantastic hack and slash adventures.

Definitely a great Ys game (6th to play so far). More of the same with the combat system since SEVEN but more improvised from Lacrimosa. Super fun gameplay and pretty chill experience, not too difficult. Exploring the castle + city is vast but not too overwhelming. Didn't mind being 'trapped' there. Been enjoying the series tons overall. Big Final Fantasy fan and love JRPG's that have several entries. I still find Lacrimosa my top tier of the series so far. But this is close behind it. I still need to check out Nordics someday.

It was decent overall, but didn't seem like they took it far. Quality seemed a little on the barebones side. I did enjoy the combat, it was still pretty good. The story was fairly weak, seemed a little all over the place. Around a 7/10 at most.

Honestly, the game isn't bad. It's just that it doesn't feel like a Ys game. Idk what it is, but this game feels a lot more like the Trail series, which don't get me wrong, is a great game series that I actually love, but I'm here to play Ys, not Trails. Anyways, I still enjoyed the game. It was just kinda sad for this game specifically that the company confused the Ys identity with Trails. Apparently, thankfully for Ys10, they fixed that identity confusion so I'm looking forward for Ys10, which I will play after finishing this game.
