Finished Ys Origin with the axe girl (there are 3 playable characters: Axe girl, staff guy, and claw man). It was good but Ys Seven was definitely superior. Ys Seven had bigger and more interesting dungeons, better music, more bosses, JUST GUARD. Ys Origin had DOUBLE JUMP, platforming, and better boss fights (although Ys Seven had a better final boss).
Out of the 3 Ys I've played, I'd put 'em Oath in Felghana >> Ys Seven >> Ys Origin. I'm looking forward to giving Ys 1+2 another shot in Jan when Xseed brings it over. I've tried Ys 1 once but the combat was wtf weird running into boars or something. And I gotta play VI one of these days since it's the only 3d Ys I haven't played now; but I hear it's a big step down from the others since it was the first 3d Ys and they hadn't quite got the combat perfected, so been putting it off.
