“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…”

“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.”
