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?
Doom will always be the GOAT

Not seen much doom modding, but MyHouse.wad is impressive stuff.
