The very first quest you set out on is a scripted tutorial test that's been set up by the mod's developers to help you learn exactly what's different about the game-a clever way to welcome players who just want to jump in and play. It changes almost everything about the game, from the heroes and inventory, to the enemies and UI. I've been keeping an eye on it for a while, and I've decided to compile what I believe are some of the best out there right now.
Darkest Dungeon is one of the best roguelikes in recent years, so it's not surprising that its modding community is full of so many creative people.
