Do not listen to IGN's \"However without the Circle Pad Pro, this game can be frustrating, featuring an awkward layout and a camera controlled with the portable's four primary face buttons. That an extra accessory is practically a necessity exposes the system's inherent flaws, and unfortunately damages the game in the process\". The four face buttons that control the camera are better than any FPS game for the PSP. I say that because this game has perfected those controls, meaning they control fluently; easy, steady, and in your control. The only controls that do not work are the gyroscope for balancing. They've never made any sense in this game (thank goodness this doesn't make you aim the gun with it). Other than controls, they work very well, you do need the circle pad pro to enjoy such a product.
My favorite is the Hashi game, it makes you think. You have to draw lines in between numbers to make bridges and connect the numbers together. There are several different games on there. There is something for everyone. It's a cool little mind bender.
