A decent game, but the gameplay gets extremely stale extremely fast. The story is about as good as can be expected when given the daunting task of writing a story that involves literally all the mainline (and some offshoot) FF characters. I know I wouldn't be able to do it.
The gacha system is nice, but not great. You will be at its mercy a lot in the endgame.
Gets rather grindy to get the mats to power up your peoples.
All in all, it makes me miss FF: Record Keeper.
