Super Smash Bros. Brawl meets Dragonball Z meets Final Fantasy. That's how Dissidia: Final Fantasy, the PSP-exclusive 3D one-on-one fighting game, was described by Square Enix at a recent hands-on event in London. That's quite a mouthful, isn't it? Not only that, it conjures up an image perhaps too fantastically incredible to comprehend. A bit like ice-cream on pizza.
