Well here's google translate for you, which I find amusing, I think they were talking about the game box cover though:
Was it difficult to make the same scene as the illustration in the game?
Sakaguchi: Although the composition changes somewhat, as an image, I brought it closer to the level that can be associated with this illustration as a game screen if it can be associated with it. If you are a forest you draw illustrations on the front of the background designer when drawing the background of the forest. It was an order that "make it a forest that can make this scene eventually".
Toriyama: Does not that make it a fool?
Sakaguchi: It's just not all scenes. Is it about 1/3 of the whole? This snowy field is a little difficult. It seems there is no snowy mountain.
(* There was no mountain of death at the time of dialogue)
Toriyama: This was the opposite of ordering. Actually, I was ordering "with a sword of ice", but since the sword was originally like ice, it was difficult to make it to ice. That's why I turned it into a flame.
