At first I thought this post would be so useless because, well, my knowledge of Minecraft is not really impressive, because I have just recently start playing it. I must say that I am really addicted to it.
Minecraft is a game by Mojang Studio, and was created by lead producer "Notch". The game focus on the creativity of the player. Although everywhere is Minecraft world is full of cubes, the view of the nature in Minecraft still touches many hearts.
Every player, at first, has nothing in his hand and must start by chopping down some tree with his hands(well that was awkward...) and craft the needed tools for gathering more resource and make more advanced tools. And those advanced tools is for, well, gathering more advanced resources. The loop keeps repeating, and many people not knowing Minecraft reading to this point must be thinking "then what the hell is the point of playing this game?". The answer is the creativity. Minecraft is full of creativity. If you have enough imagination and enough patience, you can make the very simple things like a boat, or a plane, to an extremely complicated things like a spaceship or space station.
Minecraft is not focused much on its Singleplayer feature, but Multiplayer. The Multiplayer feature can provide many people, upto 64 at once, a personal world, personal script, and personal right in that world. You make modification (aka "modding") to your server so that it allows you to make a spaceship, a plane, or a boat that will actually fly/sail in that world, or you can make up shops. Summed up, Minecraft is a creative First Person game, with the feature of RPG(You can level up, get skill, killing monsters for items, crafting items), building game(duh, almost every cube in Minecraft can be placed on a surface), and communication(people can chat and help each other to build, hunt, or even PvP,etc...). If you are not a hardcore player who seeks extreme graphic, rushing gameplay and realistic sound system, you can always give Minecraft a try and be careful, because you will be addicted.
