You all brought a lot of points and made an interesting discussion. Error tried to explain why Diablo is so much different than Minecraft as an example. But the original point was that Spike told, Minecraft has no gameplay and I just told you, that it has a gameplay mechanic, similar to Diablo, no matter why you like one of these games more or not, how art style, music or content differs. The point is: it has a gameplay, that comes just with a higher degree of freedom.
Because of that it is a game and not a movie, not an image, not a music and no magazine.
