FFXV - Episode Duscae Is Not Gonna Be In The Final Game

[VXIII]

"Tabata-san mentioned that the area in the demo is just a small part of the Duscae region. The whole region will include some cities and towns and even old ruins in the full version of the game. The whole world of the game is about ten times the size of the whole Duscae region."
