The game is good overall and was fun, but you can feel the limitations of the PSP in the gameplay. Accordingly, some missions were unfair and without save states it would be really exhausting to have to restart them every time. The attacks on the empire buildings you conquered were annoying (I didn't realize you had to save and reload the game to make it stop) and the empire missions were unfortunately too repetitive.

Story-wise, the game is okay, the protagonist is quite likeable and most of the other characters are also okay and not annoying, but you can usually predict their development. The story itself is not particularly exciting and you can always guess what will happen next, but there was still enough variety and different locations.
