What can you say about Fallout 4? it's a great loot shooter with some rpg elements but it got dumbed down to hell, and back. It lost it's entire skill system and was simplified into attributes and perks. Sure they added some gameplay elements from popular vegas / 3 mods but complexity went out the window in return. You lost the ability to use various kinds of ammo and weapons and gear no longer have durability, save for power armor.

If you want a proper fallout experience you only have two choices, Get mods to reintegrate the cut roleplaying and complexity elements. Or get fallout 3/ new vegas, there's even a revamp mod out that combines both into one game if you have em both (english version only) you have a blast with that~
