I know most of the Bethesda RPGs have massive mod support, and there’s games like Minecraft that have more mods than anyone can imagine. I would consider those games pretty playable in their vanilla states. Would you say there are any games that were “saved” by modding? Or that are still kept alive by thriving modding communities? What are some of your favorite mods?
Civ 4 had a great modded scene. The Colonization remake/spinoff in particular has a must-have mod in the way of The Authentic Colonization. The main game, though, had loads and loads of incredible mods. My personal favorite was the Ryse series of mods, which tried to more accurately model the rise and fall of civilizations via various mechanics. I have a lot of hours in the random map variant of it, Ryse Rand.
