I have been on the mobile gaming spree for a long time, and some of my favourites always were the ones from Square. But much like Final Fantasy Record Keeper, a game that was very dear to me and the global version was shutdown (even though it didn't have multiplayer anymore and was basically an offline game), now, Dissidia Opera Omnia also gets the boot. I have played it on and off since release, and it was such a magical gacha game. I managed, as a free to play player, to gear up to max all my favorite Final Fantasy heroes! It was fun and engaging! It was special! So what if you can't put the effort or the money to keep the story going, to keep making more events, or new characters. I personally don't care, and I think most of the fans don't care aswell, as long as you keep it available! Let people keep playing what is already available, because you will still keep getting new players who enjoy your series. Just not the money. And if there is no money involved, why make it offline and available for all? If there isn't profit involved, it doesn't matter, even if it doesn't generate loss either. And this is what's wrong.
I think we can change it, we the players, the free to play's and the whales, the dolphins and every other sea creature used to name money spenders. We can change this, and hopefully make an example for other gacha games!

PS: Look at Destiny Child, it ended service too, but you can still install it, and see the characters you got along the way and play their stories and interact with them. It isn't that hard is it Square? You have way more funds then their Dev's Square. You have much more "manpower" than they do so why so reluctant to make it happen Mr.Tetsuya?

PPS: REMEMBER MOBIUS FINAL FANTASY TOO? Oh and remember how sorry they were when they shutdown global record keeper? "Oh we are very sorry to be shutting down this amazing game. But fear not! We have more games that you can spend your money on microtransactions :D"
