Out of all the FFs that you played, which one has the most lost forevers?
What is a lost forever? It's basically anything that becomes unobtainable at a certain point in the game and always stays that way. Some examples are the Sylph Summon in FFIV, getting Shadow in FFVI, the treasures in Paul's house in FFII, and the Trine Enemy Skill in FFVII.
It would have to be FFVI because there's so many Rages that you can lose the opportunity to get. There's also Mog's Water Rondo, Shadow, Strago's Lores and so many other countless things.
