But then it isn't Final Fantasy? I have never understood why people always want Final Fantasy to change things like the battle system. It is the single thing to completely turn me off the latest games.
I don't think I ever see people saying Zelda needs to change its battle system, or Tales games. Why does FF need to change what fundamentally made it FF in the first place? By all means make games like Demon Souls if they want. Just don't call it FF.
Final Fantasy has always been about changing itself every few entries and Square has celebrated this fact.
Does that mean it should be like Souls? No, but it is something that has come to be expected and something that Square does trumpet and something fans rightfully look forward to seeing.
