Crisis Core is a prequel to Final Fantasy VII, chronicling the exploits of SOLIDER enlistee Zack. The core plot will still be largely enjoyable for any PSP owners looking for a quality role-playing game, but the finer details of the overall story will resonate only with players who finished the original game. The writing-especially in terms of character-is just as strong as it was so many years ago: prepare for some tear-jerking moments towards the end of the title.
Aside from the story and characters, though, very little about Crisis Core will feel familiar to fans of Final Fantasy VII. Though the battle and character development systems feature materia, that's where much of the similarity ends. Square-Enix has taken an admirable gamble with the changes to the system, but whether said changes are for the better, though, is a matter of personal tastes.
