Final Fantasy was a game made by a company that was going out of buissness so they called it 'Final' Fantasy because they thought it was going to be their last game. However the 13th game in the series was released early this year.
Final Fantasy Unlimited is an anime. Its about two siblings whose parents ahve disapeared so they sort of have to world jump to find them agian. I got bored with it.
There is also a movie (CGI) called Final Fantasy Advent Children.
