A great game with an improvement over the previous Ys.
The overall battle system is fast paced and very entertaining. With all these elements including the new party system brings a new experience into the Ys series.
The graphics are bright and amazing. All of the characters and maps are 3D in contrast to the previous Ys, where the characters were pre-rendered 3D sprites. The environments are lush and plentiful. The only downfall is that some of the larger models show visible pixels. Regardless, Ys Seven shows the full graphic capabilities of the PSP.
Considering how great the game was in general, there were some flaws. As mentioned above, there are visible pixels shown in large 3D models. In large areas, there is a slight lag when the screen fades in. However, the load time was a huge improvement over the previous Ys on the PSP. It is also unpleasant when you have a desired party but you lack the attribute needed to defeat a certain monster so you would have to switch your party member in order to kill it. The controls are also a minor flaw. You use skills by pressing R + X,O, triangle, or square. However, sometimes it reads the X,O, triangle, or square button first therefore it activates the function of that button without using the skill. The same concept applies to defending. To defend, you press L + R. Sometimes you would press L first and then it will activate your Extra Skill if your gauge is full. To fix these two problems, you would need to press R first followed by the next button. Most of the time, you would forget to press R first.
Overall, this is an amazing game. It is great for Ys fans and even newcomers. Although the only thing that segregates this game is that it is currently only available in Japan. It is actually possible to playthrough the entire game without any knowledge in Japanese. The menu, interface and much more are in English. If you import Japanese video games, this is definitely a game worth checking out.
