Minecraft is a sandbox game, which means it has no general purpose, no clear objective you need to discover everything yourself. My opinion is that it's crap when you play it alone, but with a friend or two it's a fun factory. The game isn't about being hard or easy, it has unlimited potential that is limited ONLY by your creativity and imagination, you can build all kinds of things there, I personally like building myself Castle/house hybrids with big rooms and several floors. Darkness is something you need to watch out for, at night skeleton archers, zombies and creepers (green things that explode when they come to you) will spawn and most of them will be burned by sunlight. What you can do against them is mine for iron and chop wood for trees, with enough iron you can make armor, weapons and a shield.
