My girlfriend got this as a gift for me today. I absolutely loved the opening sequence, as it is much darker than anything seen in recent Japanese RPGs. But as soon as control was turned over to me, I quickly hated the game. Unfortunately, since this was a PSP game, almost every single room you enter has a brief loading screen. Every town also. The entire game is highly compartmentalized and to walk from one area to another that is in very close proximity can involve three or four transition screens.
After about an hour I was ready to trade the game in, despite the rather clever combat mechanics. I went out to dinner with my girlfriend, and decided to give the game one last chance as I settled in for the evening. And suddenly two hours had passed. Although hampered by its PSP roots, there is a surprising amount of depth to the game. Raising chocobos, upgrading magic, upgrading skills, very lite RTS army battles, etc. Plus, the combat can be surprisingly difficult if you wander into the wrong place at the wrong time. I also met an adventurer who rattled off about 15 different locations that seem to be side quest dungeons filled with all manner of high-leveled horrors.
The game limps along technologically, but it is much more adult, and possibly addictive, than the recent Final Fantasy offerings. We'll see how it holds up.
