Yeah, the PSP version looks so damn good, it's incredible how they were able to mess it up this much.
Example: In the PSP version, if you just spam attack with Cecil and Kain, you kill the Mist Dragon before it even transforms once... and it does 1 damage to you when it attacks. Did they even playtest this thing?
Also, they copypasta'd the GBA translation... but The After Years, which is included with the PSP version, uses the DS translation for the flashbacks, which is just really jarring.
To top it off you get some ill-advised 3D "cutscenes" that look like they're from the PS1.
