Final Fantasy Resonance is looking like it's going to be a huge celebration of the series, featuring characters from across the entire history of the franchise. Almost every game is represented in some way via the game's fancy Visions system, which lets you have a summonable character at your back at all times.
However, for those in the know, you'll know that this is actually a semi-remake of Final Fantasy Brave Exvius, which is a mobile Final Fantasy game that included a lot more crossovers. And, due to the two being very similar, someone has already made a mod that lets you turn any of the 1,800+ units in Brave Exvius into a Vision in Final Fantasy Resonance.
This mod was seemingly created by a team called FFR Vision Studio, and it will allow you to drag pretty much any of the units in Brave Exvius and add them to Final Fantasy Resonance as a Vision. Unfortunately, you do have to give said character their own movesets and abilities, so it's not quite drag and drop, but it does allow you to have some pretty wacky crossovers in the FFR demo.
We played the first HD-2D Final Fantasy game...
