Rival

I think Minecraft needs a mob or enemy that has very similar skills to the player. One that can sprint, jump, attack with different weapons, and has unique attack patterns. Said rival can spawn anywhere at least 100 blocks away from your bed. This keeps the game fresh, and gives the player a unique challenge that tests their own skills. It’s almost like PVP but with AI instead. The mobs right now are really linear, bland, predictable, whereas adding an adversary with nearly identical skills to the player would bring excitement. Think of it as a meta knight to your kirby, or a protoman to your megaman. Having a rival you randomly encounter throughout the world that you’ve had previously encountered time after time would add a feeling of eagerness, like “we meet again, this battle will be better than the last”. Look at the manhunt series for example. Yes they’re beating the game, but the random fights and encounters kept the game fresh and exciting.
