Square Enix eschews the use of in-house Luminous engine \u2013 the Final Fantasy VII Remake uses Unreal Engine 4, instead. When the Final Fantasy VII Remake was announced, there was a lot of speculation over how much would change from the original. The answer \u2013 as was widely anticipated \u2013 is "pretty much everything". We could argue back and forth over the pros and cons of that until the Chocobos come home, but one thing very few people were expecting was the engine choice: the Final Fantasy VII Remake uses Unreal Engine 4, in place of Square Enix's in-house Luminous engine (which powers the next main-series release, Final Fantasy XV). https:\/\/www.youtube.com\/watch?vA3sBZ5Nr4hc It's certainly more cost-effective to use in-existence toolsets than it is to engineer one from scratch, although it could be argued that the cost of the Luminous engine has already been sunk in the production of Final Fantasy XV. That being said, it's traditionally quicker and easier to progress development with a pre-existing solution, and there certainly won't have been any shortage of developers with experience of the\u00a0Unreal Engine. The fact that the Final Fantasy VII Remake uses Unreal Engine 4 is a bit of a surprise, but when you see the results in the recent PlayStation Experience trailer above? It's hard to argue that it's anything other than a smart decision. Let's just wait and see how it plays. Source: Epic Games ICYMI, the Final Fantasy VII HD Remaster is also out now on PS4.
