Meaning of life?

Recently I have been playing a game called Minecraft. In the game you run around the world building houses out of materials you mine just to survive to the next day. The catch to this game is that there is no purpose and no way to win, so why do we play? Life could be viewed in the same way, as a journey without a goal, but we still choose to live. Is the purpose of life to just survive to the next day or something more?
