One area that Final Fantasy fans in particular can look forward to is the inclusion of many fan service elements in Version 2.0.
Yoshida personally feels that FFXIV should be a fan service title. They're adding elements from past FF games, recreated with FFXIV-level graphics and in the FFXIV world style. As an example,
you'll find a Crystal Tower in Version 2.0. This, of course, is from Final Fantasy III. The Mado Armor (Magitek Armor) that appears in Version 2.0 is pretty much the same design as that of FFVI. He also said to expect an Ivalice and the FFXIII world in FFXIV form. Yoshida hopes that this type of fan service gets players excited as they wonder what game's "essence" will next be added to FFXIV.
