Jesse Macartney actually does a surprisingly good job of acting in this game. If you liked KHI, then you should definitely at least rent the game. As for buying it, it's up to you. The difficulty isn't all that great (beat it in 28 hours, and touch it for a week after that), even in Proud Mode.

Alot of the Platforming is done away with (both a good and bad thing). The plot is EXCELLENT, even if it plays it like the first. (Fast, slow, REALLY slow, fast, then shoved in your face, then it's the final boss)

Alot of the smaller things will warrant you to have to rent this multiple times, especially after the game is over. Seph, completion of Synthesis, special ending, etc.

Really?! What games do you people usually like?
I'd be lying to you if I told you I liked any of the FFs.
