The game does stumble a bit with its battle sequences and slow start, but I would recommend Endless Legend to anyone that is a fan of the genre, or even newcomers who are looking to try it out.
While you're busy destroying your brain to figure out the game's logic, you will at least have a beautiful environment to look at. Unfortunately, graphics alone do not make a game great.
My final opinion and score for this game really comes down to the audience. If you are a fan of Japanese pop culture, or you are an otaku yourself, you are sure to find something to love in this game.
...but for those who give it a chance, you'll find what I believe to be one of the best stories in video games of recent memory. Even if you have to seek it out on PSP, it is most definitely a game worth your time.
If you can deal with the game's difficulty, which isn't off putting but not exactly new player friendly, Abyss Odyssey is definitely a game worth a shot.
