Fallout 5 can be the most immersive game in the series to date, but it will need one mechanic that didn't make the cut for Fallout 4. While Fallout 4 did have some good ideas, such as removing weapon durability and adding the settlement feature, the game wasn't perfect. The next Fallout game can take elements from all across the series in order to form the best version of the post-apocalyptic RPG. Just because a mechanic was dropped at one point, that's no reason not to bring it back later, and that's particularly true for one roleplay-heavy feature.
