I'm at the last level of the game now. Overall the game is great. Story is interesting has you go on. Dialogues are very funny. Battle system is very good too. All the power up, skill and magic customizations with special points make the game stand over most average RPG.
But...the sad part...The fps is not very good. I estimate, that you'll get around 18 to 25 of framerate, which is too noticable. Because of this all the towns are a pain to navigate and you just want to leave them as fast as you can. There's no anti-aliasing, the textures are too blurry up-close, there is clipping almost everywhere. On top of that, there are bugs when you fight major bosses. At two occasion the game just froze during those combat. Since it can take some times doing them...
In conclusion this is a great game very badly ported from the Dreamcast. If you can pass all those problems the game is still fun, but you have to elevate your tolerance from time to time.
