So i just finished the MC and here is my thoughts about the game.
So the game is missions type so its not an"open world" but the map of each mission is kinda enough to give you some exploration.
The game play is not completely strange for FF game but unique and i think its a good template for next action/rpg games in the future. The playstyle is fun with a small leaning curve, many classes and as usual starts from the basic classes up to advanced one to the experts classes.
Bring a friend with you maybe even two enjoy the story and bosses fights i guarantee you will have more fun playing with friends.
