Build a house, explore, craft/obtain all the items in the game, slaughter everything on your property, level up to max, stuff your face with food, become Old McDonald and make the best dang farm ever, and have an underground tunnel lit by lava behind glass, then adventure into the Nether, deflect Ghast bombs back at the Ghasts, make friends with the Zombie Pigmen only to kill them all later, gain as much materials from the Nether as possible, return home, repeat
