It looks fantastic in my opinion, I just don't see it as practical or actually useful for actually playing a game. Still not sold on actually owning a piece of kit like this.
The fact that you can't even find a game with that number unless owning DLC is a bad idea though. The matchmaking should just kick you out of lobbies that pick to play those maps, not block you from any lobby when they might be playing a non-DLC map.
Crazy. Its expected to be 90 million with all the other platforms involved as well - for one game that is a huge number. It was a really good invention from Mojang and I am sure they are happy with how it turned out.
