I think for the most part this is the direction Ys has been on for a long time now. It all started with Ys 5 imo. Now there has been 4 Ys games where Adol is a red head "Link" that can jump. I like both play styles imo.
I have to agree with you wyrdwad. While Felghana is superior in nearly every way, there is still something Compelling about Ys III. I still play it even though I can finish it in less than a day. I have the soundtrack saved on my mp3 player and I listen to it all the time while I'm driving. But I still have to say that my favorite piece of music from the series is First Step Towards Wars from the first one. I don't know why, I've just always loved it.
That's why Deuce rigged the Turbo Duo Soundtrack to work with Ys I & II Complete(he did one helluva job too). Those Midi mixes or whatever they are that come with the games suck. It just isn't the same unless you play it with the Turbo Soundtrack.
