ONE OF THE GREATEST GAMES EVER MAYBE THE BEST GAME EVER :D
MY 3 TOP REASONS AND 3 EXAMPLES
REASON1: It's strategy based combat makes the game harder to beat and easier at the same time.
For example when you fight Sephiroth you need a good strategy to beat him or else he'll kick the crap out fo you.
Reason2: The hidden parts of the game
SUCH as Emerald underground in the ocean not many people suspected that and checked what the big green ship as some people called it was. ANother one were the Dragons or I forgot their names in the sky and in the water
Reason3: The villian
not really a villain just doing what ever he wants is the one the only SEPHIROTH:twisted: HE IS THE BEST VILLIAN IN ALL THE GAMES EVER NO ONE CAN OP HIM8)
