Oh god, Ys III. That's the Zelda II of the series - literally, the rest of the games are top-down action adventure... sort of, while this one went the Zelda II route. I personally love it even if it's incredibly freakin' unfair. (I'm a bigger fan of the remake, Oath in Felghana.)
The first two Ys games are... good, but the way you attack enemies is pretty strange. You don't have an attack button, you just walk at enemies in a particular way. I don't remember if the DS games use the "use a button to slash an enemy" controls that later games used, but I doubt it.
Watch some Youtube videos to see if you'll enjoy the DS remake.
