In spite of my last comment, I wish to heartily support this release. It's a good game. Buy it.
I think my only problem was that my expectations for the game were too high. I should have learned more about it before I played it. You should know that:
a) The entire game takes place inside Darm Tower.
b) Despite the title, the plot has little to do with the true origins of Ys. I really wanted a game that took place earlier, when Ys was created, or when it "vanished". Instead, it takes place sometime between when Ys vanished and the events of Ys 1.
c) I was expecting the game to be more different depending on which character you choose. I was told that each character had their own scenario, so I was actually expecting the levels and everything to be completely different. Instead, it's the same levels with different dialog, and if I remember correctly the strategies for the bosses are different, and some of the enemies(?).
If you know what to expect, you should enjoy it. If you liked Oath in Felghana or Ark of Napishtim, you'll find a lot of the same fun gameplay here, with the added bonus of getting to use projectile attacks in addition to the normal melee combat you've come to expect with Adol.
