Why not an in-game Lore Book that updates as you go along, so that the lore isn't ruined for first time players. This could be connected (very easily) to an app available on PS4, PC, Android etc so that lore can be researched outside the game environment but within the context of the current in-game situation.

Square did something similar with the Chocobo game that came with FF7 & ran on PC & WonderSwan (IIRC). You could even find things in the mini-game that transferred to the full game, like Ribbons! That's what I was hoping for with Triple Triad & the lore book could do the same. Encourage reading of hidden websites, or proof you've played another FF title.

So. Much. Potential.
