Not-So Eternal Sonata

So it's been a long week as you all are probably well aware. I spent most of the last 24 hours trying to get our Oblivion mod ready for the prototype milestone, and I've spent most of the week trying to manage a ridiculous load of projects. To finally let off some steam, I was indulging in my Friday night "play games and don't think about work" ritual, and I decided the time had come to take down Eternal Sonata. I was already most of the way to the end, but I got sidetracked by other games and the courseload of Term 2. Anyway, having finished the game, I have two important questions for anyone who's finished or at least played it:

1. What is that game about? Admittedly my play time was a bit broken up, but having just sat through the 30+ min. finale, I have absolutely no idea what happened. The storyline started off seeming generic enough, but then it went all crazy on me and I have no idea what happened. I don't intend to go into any details, so as not to spoil anything, but things definitely spiral off in unexpected directions.
2. Where are my achievement points? I'm not really certain how you finish a 30-hour RPG and get around 120 points, and then the rest are labeled "secret" so I don't have any idea what they are. Did anyone manage to get achievements other than the 12 "playing through the game" achievements on their first run?

Anyway, neither here nor there, just wondering what people's thoughts were. The game definitely has some high points, particularly the graphics and art style are phenomenal. The combat system is pretty fun for a while, but eventually gets boring (not unlike Tri-C's other offering Star Ocean: Til the End of Time). Sadly, the plot is probably one of the weakest aspects as it just kind of meanders around pontificating on the state of the world and lacks any real climax or resolution, this may also be helped by the broken economy and overly powerful characters which make the game seem way too easy. Ultimately I think it's a good game for people who are new to RPGs or just want to look at the pretty colors (which are, in fact, very pretty), but as someone who's been playing RPGs for a while, my key concern is story and I think the game ultimately didn't deliver like I'd hoped. Still, I got plenty of enjoyment out of it at the beginning so I can't really complain to much. Now, I'm off to play some more games before I have to head to bed to prepare for another working weekend. Huzzah!
