Not even the numbing Tokyo cold and sheeting rain could stop me from acquiring a copy of Final Fantasy: Dissidia right when the stores open at 9:30 AM. Fourteen hours later, after a day of furious pyrotechnic battles, beautiful cut-scenes, and untold amounts of fan service, I have this to say: The Square action game curse has been lifted.
Dissidia is a smart, stylish, highly strategic one-on-one fighting game that cannot be directly compared to any other. Battles revolve around two gauges that form the game's core: HP and "Brave", which functions as attack power. Standard attacks performed with the Square button reduce HP, but the "Brave" concept introduces the core twist -- Circle button attacks steal your opponent's Brave, adding the total to your own. The higher your Brave, the more damage your standard attacks will do to the enemy's HP. Deplete your foe's Brave entirely, and they "Break", causing them to lose the ability to do any damage at all. Since Brave drops every time you land an attack, and gradually rises again when it reaches zero, battles have an inherent tug-of-war feel unlike any other game I have ever played. The system is simple but deep, and adds an extra layer of cerebral strategy atop the standard fighting game model.

The fact this has vanilla Dissidia instead of Duodecim tells me not to take the list serious. Duodecim is obviously the superior since it has the same content (story included) from the first game and (much) more

After reading all that I am really excited for this game to release state side.
Yup
It seems that once Square finds a cool battle system, they stick to it. This seems like a gathering of boss battles from a Kingdom Hearts game, just with new skins.
I just hate how everything freezes at the end of the battle, that's so uncool. And where limitbreaks were carefully scripted animations in Final Fantasy games, this just seems like banging swords together, back and forth. Just banging them together like the way children plays with actiondolls.
Really amazing game, specially for FF lovers, this game has excellent cutscenes, both, prerendered and CGI. I love this game already, even when I can't understand a thing they say in cutscenes or the menus, I still play it and love it :D god bless PSP.
