Fallout 76: 8 Mechanics Fallout 4 Ditched That Must Return
8. The Levelling System
This one is a little debatable, hence it's position on the list, but the complete removal of the skill-levelling system from Fallout 3 and New Vegas crippled any sense of progression the game had to offer. Not having any incentive to develop your own skills made the game feel a little... hollow.
Every character you made was a carbon copy of the last, with there being no need to specialise. You no longer had to commit to lockpicking in order to get into tough safes, and instead simply chucked a couple of the incredibly disposable perk points into the perk tree.
The perks in Fallout 4 were largely circumstantial, and had little to no impact on the way the game was played, or how the player interacted with it. A lot of fans hated the fact there was no point in the game where their choices in character creation mattered. No skill checks or anything.
The system in Fallout 3 and New Vegas already incorporated the perk system from Fallout 4 in a way, so returning to the skill system seems like a pretty easy implementation. It would certainly make repeat playthroughs more enjoyable.
