hated an emphasis on scavenging and building instead of storytelling and atmosphere
Agreed on the building. If I wanted to play Minecraft, I'd fucking play Minecraft.
But WRT scavenging, I initially (when playing the 3D Fallouts) hated the weapon degradation. Like, I have a gun. Why can't I just use it? Eventually, I grew to appreciate it. Nothing more terrifying than being at the lowest level of a vault, and your weapon suddenly gives up the ghost. From a narrative perspective, it makes perfect sense.
So before FO4 was released, I was thinking they'd do something clever with it. Like, at pristine condition, your weapon looks ace. As it degrades, you start to see the blemishes. By the the time it is completely unusable, the barrel would get all bent up, duct tape and all. Instead, I just collect some random shit and can craft a scope for the weapon. Whoop-de-doo.
