Now I am playing like 3 months. Found several Spawners, villages, libraries, mineshaft, ideal place for Netherportal and lot of goodies.
I have played almost a month in easiest mode to secure all villages and so the villagers from mobs. Digged a lot and builded 1 house in every village for me. Also builded 2 Spawner xp system 1xSkeleton and 1xZombie. A big mob grinder. Builded a wall around villages and created iron golems to protect the villagers. After all that began to play in hardest mode Already have nice equipment and great enchanted tools. Now preparing for the end. Thanks for sharing
