Cheesy orchestral score? Check. OTT landscapes and set design? Check. Enormous swords? Check. Yup. It's definitely Square Enix. Definitely Final Fantasy.
The PSP fighting game, first released in Japan late last year, will be out in the US this Summer and in Europe in September. Why it needs a trailer, I don't know. Maybe one or two Square Enix fans have been in a coma since 2006, and only just came to.
