Before Minecraft was developed by Notch he developed a game called Minecraftia. It was almost the same as Minecraft but the mobs get smarter and learn from battles. The game Minecraftia was Minecraft 1.0 except the mobs evolved and got smarter but everyone that played the game didn’t like the game so Notch shut down the project. He called the project Challenger Minecraft. The only way to get the game Minecraftia is to find someone that has the game and buy it from them. Then you can play it but that is the only way to play it.
