"Square Enix had initially trademarked Dissidia Prologus a while ago and we weren't too sure what exactly it meant. Come January and Square Enix released a great deal of information regarding Dissidia 012 Final Fantasy, including character reveals and details on various gameplay mechanics. What came alongside the string of announcements was Dissidia Prologus, a demo featuring a glimpse of Dissidia 012's story and gameplay.
Unfortunately, the demo hasn't left the best of impressions since it actually costs 300 yen to purchase and the thought of paying for a demo is just like paying for those sample tidbits at the supermarket. Surprisingly, there is plenty in Prologus to warrant that little extra change."
