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?
Risk of Rain 2 has a fabulous mod scene, with a lot of ways to make the game more wild - both in terms of power fantasy and in terms of difficulty - as well as modding in playable characters from other games, like League of Legends and Tomb Raider.
Slay the Spire also has excellent mods, so much so that the developers worked together with a mod team to creator a fan-made expansion.
