I love the Ys Series, Felghana was a nice stop along the way.
The achievements are a slog though.
You get a lot more direct control over Adol in this one so you're not just bumping and grinding on enemies, (Though I do miss that part.) You can swing your sword, use mana attacks and jump now. The last boss sucks as usual.
Onward to Memories of Celceta!
