Nostalgia is a tricky thing, but people have to remember that sometimes our past experiences paint out tastes. Sometimes we appreciate a game because it was a part of our lives and that allows us to overlook glaring faults and problems. I love my FFVI and it's perfect for me, but it doesn't change the fact I know it can stand to have several improvements. The "you only love it because of nostalgia argument is often a weak argument, but there have been times I've met people where it has been a valid point of their reasoning. Course it can be hard for people not to fall into this trap, especially with RPGs because the genre is so varied and has changed so much that value dissonance is quite common.
