THe UE5 version the intro of the history it quite interesting showing how you chatacter can change the appearance.
But, making it a zombie like scenario it kinda different. Specially that its going to be the history from here til end.
Meanwhile in the UE4 version, is more about zealots, thiefs, conflicts between factions, that make it more interesting, plus,the map is very (well the npc dont do much) alive. THe exploration is more fruitful because you get body parts and cosmetics. But the intro is to weird, rigth direct with weapons.
Aaaaannddd got stuck in the Liquid Gold mission goingat midnigth to see who is the smuggler.
So far the i have being enjoing more the UE4 version.
