1.Its repetitive. In vanilla, you end up doing basically the same thing over and over. I do understand there are custom maps and such, but for the beginning player who does not know how to access this(even though they may know about it), Minecraft gets really repetitive fast.
2.Its over exposed. Like I said, the only thing more exposed than Minecraft would be Minions. Atleast Minions don't have their own aisle in the store plus a whole clothing section. Walk into Target or Walmart you'll find a crap ton of Minecraft stuff in the kids section. This all good for the fan of Minecraft but seeing it everywhere makes me go "uuugh".
