Final Fantasy is a great series but what sometimes pisses me off are some of the lost forever/only obtainable once moments. Such as FF8's and FF9's way of closing most of the cities on the last disc. I mean you could use a guide but if mess up you are never getting those items unless you reload the game. Plus, I know these moments encourage players to replay the and add some challenge to the game but they can still be pretty annoying. What are your moments when this has occurred?
