To give credit where credit it due, Chronicles offers a number of presentation options. Both games are playable in Chronicles and Complete versions. Chronicles offers a kicked-up presentation, while Complete offers a more "retro" look. Either works - it's just a matter of taste. Either way, Chronicles looks great. The sprites are bold and really stand out against the backgrounds. There's a "sameness" about certain areas, which has some impact on gameplay, though the issue isn't entirely because of visuals.
Music has always been one of the series' hallmarks. Though not as well known as other games, Ys' soundtrack always seems to deliver one or two memorable tunes. Each game features three soundtrack options. There's the original 80's score, the remastered version released in the "Complete" version a decade ago and a brand new version. All three sound great, though I tended to stick with the newest version.
