Shining Sunshine said: Why is KH3 on Unreal Engine 4 when they have this beast? Click to expand...

An "engine" is only as good as its support. It's likely that the R&D team creating the engine and toolset is able to give direct support to the developers using it more quickly and efficiently in Tokyo where FFXV is developed in the same offices as Luminous, but the Osaka team making KH3 could face difficulties getting that same level of support. If they find it more efficient to use UE4 and rely on Epic Japan to support the team's technical needs with regards to the engine, that makes sense.
