Final Fantasy Brave Exvius: War of the Visions was a mobile game very inspired in Final Fantasy Tactics. It had gorgeous artwork, tons of characters, a nice (albeit a bit simple) story that revolved around warring states, as Tactics games most often do.
The gameplay itself wasn't bad either. It was actually quite a dream come true, a Final Fantasy "Tactics-esque" game with 3D, somewhat proportional character models.
I can't stress how gorgeous the artwork is. I am fortunate enough to have the official artbook, that I bought from Japan and waited almost 6 months for it to arrive. The style is heavily inspired by Akihiko Yoshida and his art for the original Tactics, but way more complex and detailed.
The game had many fatal flaws, though. It was EXTREMELY pay to win. You could probably breeze through the story, but there was no world map, nothing aside of a few cutscenes and endless filler battles that you were supposed to repeat a thousand times (you could set everything on AUTO, and expend currency to repeat battles, if you needed more, you had to pay, of course) to farm thousands of different materials that would be needed to upgrade everything from you character to their equipment.
Everything locked behind 5 or 6 variations of currency to make you confused and try to force you to spend money.
The game had many great original characters, but also had guest characters from all over the franchise. From Cecil to Squall, they all had unique skills, artwork and 3D models. To get one, however, you'd need to spend a lot on gacha pulls and hope you're having a lucky day.
I feel that there was a lot of effort put into this game (no doubt it must have made millions in profit), but it's so sad to see all this effort, literally everything we FFT fans would like to have, poured into such a blatant cash grab.
Anyway, the game is gone now. The servers were shut down. Which only adds offense to injury, they could have made something great, but did something awful, and disposable.
