Yup, I guess that's true. Sunset and Ratchet look pretty much the same.Its the same engine, they probably reused some assets and textures. Like the fur you mentioned. It's the same fur in sunset. And it's physics based, and it's customizable.
No one would look at both and claim one looks "a lot" better.
And yes sunset is one of the best looking titles on X1. Second only to Ryse and Forza..
Same engine and all right?
TLOU and UC4 looks the same too, same engine.
