Eternal Sonata was released on the XBOX360 in 2007 and was largely overlooked by gamers. The game is now being given a second chance to appeal to most gamers. For the most part you're getting the same game you got a year ago with a few extras. It's a little hard to say whether or not it's worth getting a second time if you already played it before.
Eternal Sonata is largely focused on Fredric Chopin. He lies on his deathbed, unconscious and dreams of a world. In this world, those who can use magic are terribly sick and dying of illness. The citizens of this world are also in a bit of despair as Count Waltz continues an unpopular rule and stands against the people. The story is actually not a bad one. Unfortunately it isn't always presented as well. In the first place, the voice acting just isn't the best out there. Some of it is rather dry and emotionless. The voices themselves aren't bad, but the emotion is almost non-existent in most of them. The story also moves somewhat slowly, and that's strange given that Eternal Sonata is not a very long game. Also, some will probably not appreciate that the game eventually becomes incredibly preachy throughout its final moments.
While it may not present its story as strongly as it could, it's gameplay is still as strong as ever. The battle system for Eternal Sonata is one of the most inventive in the genre. It's a turn based game but adds an active element. When a character's turn comes up in battle, they all have what's called an action gauge. When their turn starts the action gauge counts down. During this time you can do whatever you like until it runs out. Mostly you'll be mashing on the attack button to get out as many hits as you can. You can also execute special attacks. It's a very easy battle system to grasp, but it's hard to master. This is because the battle system never stays entirely the same. You also have a party level that increases as the game goes on and it changes how the battle system works. For example, at Party level 1 the action gauge decreases only when you move, and stops decreasing when you stop. When you hit party level 2, however, the action gauge never stops. It adds a lot of variety to the game but also makes sure that battling is always interesting.
The battle system also has special moves that characters can use, but they change based on whether or not you're in the light or the shade. Some enemies will also change form depending on if they're in the light or the shade. It adds some strategy to the game, but in the end Eternal Sonata still feels like a button mashing affair. Along those lines, the game is not that hard. When you really grasp the battle system and learn it, accumulating large amounts of damage becomes consistent.
There isn't a whole lot that's been added to the PS3 version, but some of it is rewarding. Characters can change their costumes, there are now two new playable characters who were unplayable in the 360 version and a couple of new dungeons. On the other hand, Eternal Sonata is still short and largely linear game. It's nice that there are a few more extras than the average port but they still don't make a huge difference in the gaming experience as a whole if you have the 360 version. In short, if you haven't played Eternal Sonata and you want to, the PS3 version is the better choice. If you've already played through the 360 version, however, there's not much here to entice you to play through it again.
One huge noticeable difference between the PS3 and 360 versions, however, is by far the visuals. The animations are smoother and more vibrant on the Playstation 3. Eternal Sonata was already an incredible looking game to begin with, but the Playstation 3 brings out a lot more in the visuals.
Musically, Eternal Sonata still has some of the best in the industry. You'll even hear some of Chopin's own music at certain moments and get a little bit of a historical background on him. Eternal Sonata's biggest strength is easily its soundtrack.
In the end, Eternal Sonata is still a good game. If you have it on the 360 it's not really that different, nor does it include enough new content worth making it worth a second buy, but for those who haven't played it, it's another chance to play a pretty good game.
