Vanilla Minecraft itself is not particularly crazy in this day an age but a common theme with games like this is that the community really gives such an unending plethora of content to explore it's as if it were a game engine in itself. Building and redstone aswell as its modding potential seems to be really impressive parts of the game whereas the survival and pvp aspects of the game seem to be really basic in comparison. On the other hand the soundtrack is in a league of its only rivalled by a few other games for me.
