While most Final Fantasy games take place in their own worlds, the franchise is still linked together through several iconic factors such as Chocobos, elemental crystals, and powerful summons. The series established many of those tropes early on but not all at once. Summons, for instance, weren’t added until Final Fantasy III (the real Final Fantasy III, not the original American Final Fantasy III). But unlike some of the other iconic Final Fantasy features, summons weren’t necessarily intended to be a major part of the franchise.
