Like the title. What games are made better with mods, and foster a great modding scene that retains momentum and delivers excellent content?
My personal favorite is Fallout: New Vegas, but games like DOOM, Half-Life 2 (really all source engine games), and Minecraft have extremely unique mod scenes. Of course, Skyrim remains a modding titan. STALKER: Anomaly is already an amazing mod project and has mod lists for it like GAMMA.
What are your favorites?
Subnautica's got a small modding scene, but it's mods are pretty good
The subnautica MP mod (not updated to the latest version) is incredibly fun
