||On the rare occasion when a PSP title turns up it's the same old routine; the customary rigmarole of a firmware update before the game will even boot, then the realisation that the battery is flat and the arduous wait before coming anywhere near to even being able to load the game...Fortunately, Final Fantasy: Dissidia is well worth the wait. It's an absolute beast of a game packed with so many features and depth that it's a wonder they managed to squeeze everything onto a single UMD. Following the masterpiece that was Final Fantasy VII: Crisis Core, Square-Enix has once again shown what the PSP can do when handled with the care and attention many publishers fail to devote to it...Dissidia is a game that sustains your interest by constantly rewarding with new features. Even after numerous hours into the game, additional modes are still being unlocked. Accomplishments work like Xbox 360 Achievements, rewarding you with various unlocks by completing different criteria. A Calendar system keeps track of your progress, rewarding you on certain days with various perks and providing a tangible real world bond to the game that keeps you coming back for more. And if that wasn't enough, extra modes titled 'Shade Impulse' and 'Dual Coliseum' are unlocked after completing the main story mode. Dissidia also features Ad-Hoc multiplayer, with various benefits coming into play when fighting against friends. As always with PSP titles it's a shame the game doesn't support Infrastructure Wi-Fi play, but there's no denying it offers enough to warrant convincing your friends to pick up a copy of the game...Square Enix has even thoughtfully put a Data Install option in there to cut down on the load times, and more importantly improve the battery life because the UMD isn't constantly whirring away...But above all of this, Dissidia is a game for fans of the Final Fantasy series. Beyond the fact it pits the likes of Cloud, Squall, and Zidane together, there's plenty of little nods that will entertain. For example, following your adventure, replete with old-school 2D visuals, the Chocobo's journey throughout mirrors your progress in the game and unlocks various bonuses along the way as you engage in battles.
