I am fairly certain that the large following attracted by Final Fantasy is that it is the largest Japanese role-playing game series. I have to admit that there are many games that I enjoy more than a Final Fantasy game, but those lack the community and support that the Final Fantasy series has.

Most people have different tastes, but if a person likes Final Fantasy, there is a good chance that they will like other games with a similar style of gameplay. I like Final Fantasy communities because they are pretty much the largest communities for role-playing game enthusiasts without being too broad or too narrow.
