What's been your favourite specific gameplay mechanic this generation? This is a specific mechanic that has been in 1 or multiple games that was created (or just significantly improved from previous) in this generation.
My personal favourite was the settlement mechanics in Fallout 4:
There was a significant amount of issues with it - tons of bugs - but it was the closest I've gotten to the "build your castle" from Suikoden series or "develop your town" from Dark Cloud / Act Raiser / etc within RPGs of previous generation but adding a lot more Minecraft like building capabilities and farming for supplies via main game. And it did it such in a way that it can be enjoyed as a side aspect to the main game or in addition. So if you got tired of a main quest or side quests, you could go build out your settlements for a bit then come back.
I believe I've played Fallout 4 more then 200+ hours due to this mechanic plus Bethesda games in general being extremely long for completionists like me. That's almost getting on MMO territory hours.
