I think we should call it… your grave!
Ah! Curse your sudden but inevitable betrayal! Ha ha ha! Mine is an evil laugh! Now DIE!
Real defense is best handled in-depth, or so my years of video gaming have taught me. Identify any avenue for attack by an enemy and utterly remove that avenue. Then fortify it. Then erect a string of watchtowers and beacons overseeing a vicious barbed fence that only the truly foolish would attempt to cross. Sure, you might make it, but any victory will come at a terrible cost.
I call my fortifications the Mexican border (har har!). A ragged ring of torches outside my undermined moat was sufficient in pushing back nighttime mob spawns in three directions. While it was at least good enough for me to confidently say that I never saw any monsters wandering down from the hills, I was still consistently being attacked by monster spawns from the fourth, a vast sandy plain linked to my staked out area by a narrow isthmus. Twenty minutes of later I had laid down a double row of cacti backed by a wall-and-rampart topped with an observation tower. With a water trap on each side that would either drown a mob or shove it onto the cacti. A little perversely, I pulled out all the torches from the far side of the wall so as to encourage mobs to spawn near it and meet their doom on my living barricade.
Hi, my name is Mark and I am addicted to Minecraft.
Minecraft is Lego for the Internet world: You start off on the 8-bit beach on the first 8-bit morning of the 8-bit world, and whatever you do thereafter is entirely up to you. Build a castle. Go spelunking. Don armour and sword and fight for your place in the world. Roam the wide hills. Sail across the sea. Myself? This and that, a little of everything, oh you know how it goes. A three-dimensional monument to four-dimensional tesseract, a structure whose scope includes such extremes as a glass-walled pit that dives unbroken from the surface to the very bottom of the world and a tower whose peak rises clear above the cloud deck.
The bottom line:
The only real limitation on your enjoyment of Minecraft is your imagination and available free time. This is the Land of Infinite Fun. Come on in.
Minecraft is the subject of ongoing active development and it currently released, marketed and sold as an alpha product. There are quirks, idiosyncrasies, and outright world-crashing bugs. New content is patched in weekly. Mechanics are altered, added or removed. Old bugs are fixed. New bugs are introduced. Joy. My biggest personal gripe with Minecraft is that contrary to the nature of the game you are discouraged from exploration. Monsters can – and will – one or two shot you from behind. You can’t move your spawn point and if you die at any distance from it you are left to make a lengthy hike back to the location, only to discover that your goods have already rotted away. If you’ve just mined some rare diamond it can be heartbreaking. So. That’s all of it. Go download.
