For one of the best PSP games I've ever played, I was surprised by this game at the start. It starts off as what seems like another cash in for Square Enix with Final Fantasy VII. What it ends up being is a solid title that actually adds more to the series.
First off, the combat system is fun, fluid, and stands above everything else. If this game has not been a Final Fantasy game, it would have still been fun. I feel that this combat system is what makes this game so good. I can't say as much for the level design or even the pacing but the combat shines.
The story is okay and definitely adds more than the other FF7 games that I have played. The music is okay but nothing stands out. If you are a Final Fantasy VII fan, this is definitely a game that you want to play. It explains a little bit about other events in the game but does fall flat sometimes. If you have a PSP, you should own this game.
