KCD is a very good game, and some elements are brilliant. When one considers that KCD cost less than 1/50th of RDR2, one has to be impressed with what WH delivered. (I say this with 100% sincerity/0% sarcasm.) The landscape, the writing, the authenticity, etc.
Where the $$$ is evident most is running away in Rattay vs St Denis. RDR2 handled the equivalent of Rattay race but at a much grander scale without so much as a hiccup. St Denis has more buildings and many more NPCs (walking, riding wagons/horse/trolleys).
The money spent on RDR2 was worth it just to see the PS4 handle all the things PC snobs said couldnât be done on console.
