Rough translation of the interview:
Yoshinori Kitase: "I'll like the people of today's generation to taste the "shock" that was tasted then. So, "Final Fantasy VII Remake" produced this time is not made by tracing "FFVII" 20 years ago, but by generously introducing the latest technology exceeding the latest Final Fantasy series "Final Fantasy XV", I want to deliver a new shock"
This makes me happy that this is possible with unreal engine 4 because FF7 is a HUGE game, it's a big big game. bigly. We got Midgar City, airship traveling, we get to go on the sea, under the sea, we go into space, over and into five mountains, tundras, deserts and over 50 different locations, plus we got 13 different summons. Think about that, the luminous engine in FFXV could barely get together Leviathan, it was just a terrible engine.
