Fan service? Absolutely. Fun? Unquestionably. Dissidia is a Final Fantasy fan's dream come true, the kind of crossover that's sure to make franchise aficionados giddy. Yet it's far more than just a love letter to series fanatics. Dissidia: Final Fantasy is an exuberant and addictive game in which showy one-on-one fighting and role-playing mingle so effortlessly that it's hard to pull yourself away. And the more you play, the more Dissidia keeps giving, showering you with extra features and in-game rewards as if you were in the center of a ticker-tape parade. The visual drama of battles is unfortunately undercut by some camera foibles, and the feeble narrative is out of step for a series renowned for excellent storytelling. Yet this is a generous package that offers untold hours of over-the-top spectacle that almost anyone can appreciate, even if they've never played or cared to play a Final Fantasy game.
