It’s the mostly same for the games I mentioned, it’s just incredibly easy to become OP in them so it’s not that hard of a roadblock and it still scales enemies beyond just adding in new types. NV has static leveled areas and FO4 spawns more difficult enemies the further away you move from Sanctuary. You can go anywhere right at the start, but you’re not gonna have an easy time fighting dearhclaws and cazadores at level 1.
