One of the most consequential decisions that the developers may make for Fallout 5 is whether to bring back the weapon durability mechanic. It's a Fallout feature that stirs plenty of discussion, making its potential inclusion worth theorizing about. While it is only a single mechanic, it could end up having a dramatic effect on Fallout 5 depending on whether it is included. It could end up being to the game's benefit, or it could turn out to be one of its weaknesses. Even before Fallout 5, opinions on equipment durability are all over the map.
