Subtle systemic overhauls that rebalance games: best game mods 2025

[Aaron_M]

I'm less interested in total conversion mods and more in subtle, systemic overhauls that fix or rebalance a game's core mechanics. Things like mods that completely rework the survival systems in a game like Skyrim or the traffic AI in Cities: Skylines. What are the best game mods 2025 that have offered this kind of deep, under-the-hood improvement to an existing title?
