It has many flaws, a bad story and it's still worth playing...
In spite of its advantages (interesting dialogues and characters, greek mythology and an above average combat system), it has many flaws.
First, the graphics, except for Jason, are very bad. Second, the frame rate is broken and sometimes and many flaws can be seem during the game. Third, there is too much talking in the first part of the game. The other two problems, which i consider to be the worst: sometimes the controls do not respond properly and the story of the golden fleece could have been much better in this game. To end, the creatures are very repetitive.
Why playing? The Greek Mythology ambiance, interesting dialogues and character developing system. Beyond that, the game is very easy, even on Legend. It will not take much of your time. To end, it mixes elements of an adventure and a RPG. Worth trying, but do not expect much of this game. Just try to have fun.
That's all folks.
