The problem is that the spice and flavour of Skyrim was not using the fast travel and just exploring.

With modding to add random encounters and roaming friendlies/neutral mobs, Fallout 4 was great too. Even more so recently with the flyable vertibirds so that you could get the in-game fast travel that used resources.

But neither of those can exist in a game where fast travel is a core and unavoidable gameplay mechanic.
