Try to reply with examples(and when you do avoid choosing examples that follow confirmation bias) instead of broad-unbased refutations.
Minecraft clearly demonstrates the comparitive heaviness of using voxel arrays to represent a world in contrast to a polygon mesh. This point is trivial, and is not unique to Minecraft.
Additionally I'm finding a large number of comments that begin with "No it doesn't", then either stating an identical argument to the parent, or not attempting to refute the parent comment at all. If you're doing this for "points" then shame on you.
