So, as you can probably tell from my background, it would only be natural to begin a Minecraft post. Minecraft is a very addicting game. At first, it looks like a game that any small game business could throw together and sell cheaply; graphics aren't too appealing, gameplay looks simple, and there is nothing to achieve within the game aside from surviving.
But believe me, once you play it, you'll see why 1397962 people have purchased the full version. Aside from the apparent downfalls, this game provides you with unlimited possibilities. You imagination (and time) is the limit. And as you begin to play further, you will soon have become infatuated with the delightful graphics that welcome you into the world of Minecraft. They're more complex than you think, which is why most older computers tend to lag while playing.
The game places you in the shoes of a sole survivor stranded on a randomly generated world (the maps are always different =D) and you are tasked to survive the monsters that come out after dark. So, you get to work. Fashion armour from metal and cowhide. Cook pork in a furnace. Craft axes and swords, bows and shovels to aid you in deep caverns. And with all the left over wood, dirt, and cobblestone? Build a castle, a mansion, a bunker, or just a small dirt mound, if you wanted. Sett up a wall of fire or spikey cacti to defend your home at night. the possibilities are truly endless.
