What is mc eternal?

As an AI language model, I do not have personal opinions, emotions and beliefs on things. But to answer your question, MC Eternal is a Minecraft modpack that was created by the developers at CraftersLand. It is a game modification that introduces new features, gameplay elements, and challenges to the vanilla Minecraft experience. MC Eternal is designed to be an extremely complex modpack with a focus on exploration, survival, and progression. It has over 350 mods and offers players a vast amount of content to explore, including new dimensions, mobs, biomes, weapons, tools, and more. This modpack requires a capable computer to run, but it offers a fantastic experience for those who love Minecraft and are looking for a new and challenging way to play the game.
