Square is too busy taking away the open world, the control from the player, coming up with esoteric names (preferably weather related), strange esoteric character designs and coming up with new (battle/character) 'systems' to really understand what it really was that real fans wanted.
An involving storyline, user friendly controls (stick with what worked: FF6-10's systems, as much as I hated X I can admit it had a great battle system, though not character system.. the sphere grid was pointless, counter intuitive and mapped out to a straight line, aaanyway tangent..) a believable yet interesting world/setting, the ability to explore it and interesting characters that evolved through playing the game as the story unfolded.
I really don't understand the Japanese obsession with making new 'systems' each time... why they don't just stick to what works and was enjoyed.
