Final Fantasy XV director, Hajime Tabata has come on to the official forums of the game to address the lore behind the clothing worn by the main characters. He explains that the clothing is the official battle gear of Lucis and is a special color in that kingdom’s history. Additionally, the team plans to add effects in battle on their clothing and not just be in the background.
The clothing worn by the four main characters is the official battle gear of the Kingdom of Lucis.
Noctis is a member of the royal family and the other three characters are parts of various Lucian national organisations and they are each wearing the specific battle dress relevant to their individual stations.
In the Kingdom of Lucis where our heroes reside, the colour black has historically been treated as a special colour. Because of this, the attire of the royal family and those in occupations closely tied to them are unified by having black as a base colouring. This part of the lore is the reason why the outfits of all four main characters are black. For the finished game we also intend on having their clothing having effects in battle and not just being a part of the world and its background. So watch out for that too!
Update 2: Tabata has revealed that another element that existed in Final Fantasy Versus XIII has been removed from the game.
Yes, this can be said added-afterwords because clothes Noctis and his companions wear was black to begin with. In the process of game creation, there are two patterns – one where there is a setting and game elements are determined based on that setting, and the other where we have game elements and a setting is created using these elements. So this case falls into the latter.
Those who already know a lot about FF15 like yourselves may feel these settings are unnecessary. But for those who have just been introduced to the world of FF15, these settings can be a great help in familiarizing themselves with this new world. Now let’s say you, do1pen, have been asked by someone, “What kind of a game is FF15?” It is hard to answer this question if you don’t have a clear idea what the most important theme is. The FF series comprise so many elements and it is among the most difficult games to explain in a few words. For FF15, we consider it very important to have a clear theme that you can explain in a few plain words. So my and all my fellow FFXV developers’ answer to the question “What kind of a game is FF15?” would be “a game to regain a kingdom once lost.”
By the way, in Versus 13 Lucis was set as a country of Reaper worship. This setting is a violation of the age rating criteria for games in some countries, so we cannot push these theme. To replace these theme, we have a backbone setting of “black as a special colour.” And I hope you will wait for more information to come on this.
