In a recent interview with Lead Environment Artist Hiromitsu Sasaki, which has now been published on the Square Enix blog, it was revealed that the team behind the development of Final Fantasy XV is currently working to assure that the game looks as realistic as possible.
Sasaki explained that the developers' intention is to offer a different experience in the differents parts of the world, as each location has its own climate and topography. "We really take care with the history and story behind each area, with all the rocks and wildflowers etc," said Sasaki.
"For FFXV we started creating the world terrain from the continental level, with the mountain ranges and the flow of the rivers etc. and have polished it to a level where each region and location actually has its own unique climate and topography.
"So we don't just plonk down the assets that we photographed on our location hunts willy-nilly, and actually consider the right geographical situations to use them in, looking at how this continent would have been in a certain way in the distant past and how that would make this particular piece of ground form in a certain way or things like that."
Final Fantasy XV releases later this year on PS4 and Xbox One.
