It's that magical time of the year, friends, when Japanese game companies start pulling back the curtains a little in preparation for the annual Tokyo Game Show in September. As usual, Square Enix is getting an early jump on things, showing things like an arcade version of Theathrythm Final Fantasy, new content for the arcade version of Dissidia Final Fantasy, and a spin-off of Dissidia for mobile. Yes, it's a spin-off of a spin-off. Insert meme image here. Titled Dissidia Final Fantasy: Opera Omnia, it's due out for iOS and Android sometime this year.

For those not familiar with Dissidia, it's an unusual fighting game that pits iconic heroes and villains from every installment of Square's popular RPG series in arena battles with one another. The first two games in the series were on Sony's PlayStation Portable, and an updated version is currently making the rounds in Japanese arcades. Though it's become common for Final Fantasy heroes to mingle with one another these days, Dissidia was one of the first to really explore that concept. Combined with its unique fighting system, it holds a special place in the hearts of many players.

So what's Opera Omnia, then? Well, by the looks of it, it's another free-to-play social RPG. It's certainly a spiffy-looking one, with many of the battle actions mirroring the stylish special moves of the main Dissidia games, but it's not clear from the trailer what exactly will set this apart from the other four or five free-to-play Final Fantasy mash-ups. As usual, it's unclear if this will be releasing anywhere but Japan, but given that Square has recently shown greater interest in getting these games out across the world, I'd say there's a good chance. We'll bring you more news as we get it, and hopefully some impressions from Tokyo Game Show if they're showing it there.
