To be fair Final Fantasy games i played since the first had always changed from time to time, I mean they went through a lot of systems till they ended up on PC/Androids/IOS. The perfect ones was Final Fantasy I,II and IV for the PSP now if Square released III (2d version) with psp graphics instead of the 3d ones, i can imagine how that would look like dame with 5 and 6 but...yeah.
As an adult now, i never lost my love for Final Fantasy, I played the good, bad ones and never lost my nostalgia for it. Now that Final Fantasy & remake is coming out for the PS4 i'm more than excited. They haven't lost their "purity"...yet they just deviated when we love about the original FF that we all grown to love.
