PSP:

- Two new classes: Onion Knight and Dark Knight.

- Two new Non generic playable characters: Balthier from FFXII and Luso from FFTA2.

- You can play against a friend in cooperative /versus mode now.

- New Equipment avaible from the multiplayer mode. I heard the equipment varies between cooperative and versus mode.

- New battles and events in chapter 4. Most of them involve Non generic characters that join our party, like Beowulf, Meliadoul, Agrias. You can get rare items on those battles.

- You can have now 24 units in your army, compared to the PSX 16 limit. That's just awesome.

And there's this problem with the speed when you're playing, the animations of some of your units' actions may happen very slowly. Not that much of a problem, thought.

And hey, I want a PSP solely for that purpose also, too. I'm saving money for it, and I think I won't regret it at all.
