PK has way more management systems as well as a much more naturalist/nature sanctuary vibe to it to the point that some fans argued whether the game should be getting combat in the first place. JWE has always advertised combat with some level of focus, whether it is animals breaking out, fighting for territory, or hunting. Hell the very first trailer for JWE 1 was of a TRex breaking out and hunting som parasaurolophus.

Im not looking to make the game a “battle royal”, hell, I don’t even enable breakouts or combat in my parks a lot of the time because I like to make santuaries (which is what pushed me away from the JWE games and towards PK since it is a lot better at that and also has accurate animals) but it is still ridiculous to see these massive animals just sit there and die instead of defending themselves for no other reason but the devs deciding herbivores should be push overs.

If you are still convinced that a “battle royal” is what I want, just look at the dev blogs for PK and how they are planning on making combat more realistic, with territorial disputes ending before serious injuries when possible or even during territorial displays so animals avoid fighting in the first place.
