Such mods like Project Nevada for Fallout: New Vegas and Skywind for The Elder Scrolls V: Skyrim create brand new experiences for players to enjoy.
If you’ve never given mods a second thought, for PC games, maybe reconsider them, as the mod scenes of various games are incredibly active and known for having comprehensive changes that can create completely different experiences. Personally, I never figured Far Cry 5 for the kind of game to garner attention for its mods, but here we are in 2020, where Far Cry 5 mods are the talk of the town.
The mod scene of any game is important to its life cycle on PC, and in Far Cry 5’s case, it seems to be flourishing at the moment.
