More Dungeons addon
There can't be enough dungeons in the game because that's where people like to go for exploration and loot. That's why Nico's More Dungeons is so good; it incorporates four new dungeons into Minecraft. Each dungeon has its own theme and a boss at the end of it. For example, there will be a dungeon full of rats with the appalling Rat King as their leader.
