Final Fantasy 7 was the first futuristic Sci-Fi FF game. Because of this the game though fairly good just didn't fit in with the other games, in my opinion in FF7 they took the "fantasy" out of Final Fantasy. The game was also the first and only game to use the Mteria system as a means of magic and abilities. Because of this though, all of the characters could use all of the skills and all of the magic which made all the characters pretty much the same besides their Limit Breakers which had greatly changed since their debut in Final Fantasy 6, Limit Breakers were now multiple skills learned as you progressed and were able to be used in a system copying Lufia 2's IP system which had appeared a year earlier.
