How much do you love Final Fantasy VII? If your answer is anything more enthusiastic than "It's okay," then you absolutely need to play Crisis Core. Even more so than Dirge of Cerberus, this addition to the Final Fantasy VII universe expands the fiction and has a significant impact on how you view the events of the original game.
If you were to watch a movie and periodically pause it for five to ten minutes, you would, in essence, be creating an experience similar to the one GI had with Crisis Core. This may seem like an odd analogy to make, but this game's combat system is just as uneventful as a movie's pause screen. Most of the battles can be completed without looking at the PSP's screen. With enemies exhibiting the liveliness of a stuffed sloth and your character automatically latching onto the next foe, it's just a matter of tapping the X button in succession. Gameplay this poor deserves to be tossed to the wolves, but the game itself isn't a complete loss. GI enjoyed watching it. Like the motion picture Advent Children, the computer-generated movies knock you to the floor and smack you in the face with highly stylized crackerjack action. Zack's tragic tale is also the perfect companion to Final Fantasy VII. Once you play this, you'll want to jump right back into the PSone classic. So, if you've done everything but make love to your Final Fantasy VII discs, throw on your galoshes, because this story is worth trudging through the foulest of gameplay for.
