Consider me a psycho with a hot take, but I have always preferred games that mix the enemy difficulties around in a zone. Something like Ark where, sure, level 3 Dodos spawn on the starting beaches, but a level 70 Spino can spawn not far away and you have to be sure to skirt it lest you become a healthy snack. The steady progression of "zone difficulty" has always bugged me a bit because it is just so far off from realistic. Sure, close to a settlement there would be culling of particularly dangerous creatures, but some of them would still exist (if the settlement is being responsible). And yeah, as you get farther into the wilds those sorts of cullings would fall off rapidly, but to say that there would be areas where there are no easy monsters or no hard monsters, even in the wilds, is just not accurate.

Also, you get the same feeling of accomplishment, sometimes more, when you have died to hard monsters in starting areas a bunch of times then learned to skirt aggro properly, but then suddenly you come back after being out for a while and utterly decimate them. Just feels so good.
