When the full version of the game is released, buying it now means you will already have it then. So any updates, new things added, or any bonuses added to game content will automatically be given to you because you paid for the game. I think that later on, if you want everything, you\'ll need to pay for it, but until then the game is free. So mainly, buying the game ensures that you get everything and have everything by the time the game is completed and released. Also, who knows, in the future it may go up in price more, so you may have gotten a deal buying it now, too. That\'s my thoughts at least.
