Dunia is a good engine, with a CryEngine core. Goes to show what can be done when an engine is modified with multiple iterations. On an off-topic note, I hope both Dishonored (if we see a sequel, I truly hope so) and the Evil Within use a modified version of Id Tech 6 rather than Id Tech 5, considering the improvements Id Tech 6 has over its predecessor. Optimization and amazing anti-aliasing for starters (TSSAA looks incredible, and doesn't hurt performance like you think it would). Hoping Far Cry 5 turns out as good as it looks. The map editor alone sounds incredible.

BTW, not sure if you play on console or PC, regardless, have you seen anything about FC 5 using Nvidia HairWorks? It was in Far Cry 4 (not sure about Primal) it's a pretty cool feature but is commonly demanding on hardware. Just wondering is all, I know Ubisoft have their own fur simulation tech as well, which depending on the animal in FC 4, it actually looked better imo.
