I'm a big FFT fan that played the PSX version to death and love the game but I was pretty disappointed with the PSP port.
one reason: GAME SLOWS DOWN WHENEVER YOU USE ANY ABILITY
Its kinda a love hate mix feeling. The additional characters, jobs and side stories were a nice addition but the problem above makes the game extremely stressful if you've experienced the PSX version.
This is a damn crappy porting job on SE's part.
crappy old school NES games are more entertaining than next-gen games.
