Okay. So you know Square Enix's upcoming PSP title, Dissidia 012[duodecim] Final Fantasy? Yeah, well, before that game launches on March 22, they'll be releasing a prologue through the PlayStation Network on March 15. What's this one called? Dissidia Duodecim Prologus Final Fantasy. No lie. We couldn't make this stuff up if we tried.
Anyway, Prologus will focus FFXIII's protagonist Lightning, and in addition to the Story Mode, you can also have quick battles with two difficulty levels in the Arcade Mode. You'll also be able to carry over items you unlock in Prologus into the main game. And FF fans will probably like the final bonus most of all: You'll be able to unlock a very special character in the main game Aerith!
You'll be able to download DDPFF through the PlayStation Network starting on March 15 for just $2.99. Not sure exactly how much gameplay you're getting or if it's kind of a glorified demo, but three bucks isn't really that pricey, I suppose.
