Something that really stands out to me with Fallout 4, especially in comparison with previous versions, is that until you get to Diamond City, it's almost entirely combat, other than the workshop quests. There are only a few characters with whom you can actually initiate dialogue (The Minutemen, settlers, Codsworth, and the rare wandering trader) and few of them have much to say. Once you get to Diamond City things change a bit and there's more quest variety and considerably more vivid characters but frankly my first impression of the game was a weird hybrid between a shooter and Sim City with very little roleplaying. Having got up to level 21 and gone a ways through the main story quest, things change quite a bit later on (though I still miss the flexible quest approaches of FONV), but I think the game's opening could have been made a lot more engaging for players who are more fond of conversation than action.
It seems an odd design decision. The more conventional approach to RPG's is to have a game's opening be exposition-heavy with a lot of fetch and fed-ex quests to earn experience until you have enough weapons and skills to strike out into the wild. And even with Bethesda being more action-oriented than Obsidian, FO3 and the TES games start you in or near a town where you can buy and sell stuff, meet people and get a bunch of easy low-level quests.
