If so you could do The SomeGuy Series for Fallout New Vegas. It provides several more friendly and fully voiced quests.
If you want to play Fallout 4 you could try Project Cartographer combined with Sim Settlments. That way you can fully explore all the neat unmarked locations Fallout 4 has to offer and not worry too much about settlement building.
If you are stuck between Fallout 3 and New Vegas you can try Tale of Two Wastelands and bounce back and forth between the two.
