Minecraft is a special kind of game, one that includes some creepiness. It's not that Minecraft's creepy, but it does feature odd and unnerving moments and characters. There's a raging debate about whether or not some of the scary things in Minecraft are even really real. For example, while many people assume that Herobrine isn't real, the creator of the game likes to tease gamers every once and a while and suggest that he only appears during really specific times. There are also a bunch of Minecraft maps that could be considered creepy.
While it's fun to speculate about creepy things in Minecraft, not all of them are so mysterious. There are plenty of scary things that people have discovered and created all on their own. And with the introduction of new skins and add-ons that came courtesy of the "Friendly Update," there are sure to be plenty more creepy things to come.
Minecraft is highly unique, not just as a game but as an interactive social entity. With the creation and community aspects, you get a world that is unlike anything else. Most people might be playing the happy and colorful Minecraft, but there's also a creepy Minecraft just waiting to be explored.
