Seen quite a few people claim that Xenoblade Chronicles: Definitive Edition is a remake built in the Xenoblade Chronicles 2 engine, but can’t find any evidence to support this beyond a few throwaway articles saying it ‘looks like it’s running in the Xenoblade 2 engine’ Sources?

From playing it this is beat-for-beat a remastered port, right down to Shulk’s super weird jumping animation.
