The Meaning of Life, the Universe, and Everything.
I've been playing since 1.00 but I haven't actually finished a game yet.
-I just don't want to think that there's nothing left to achieve in a world so I've only gone against dragons on hardcore worlds.
(Obviously I still have things to learn about being aggressive)
Once multiplayer with my girlfriend, primarily with sword and bow, and with pumpkins on our heads.
Once in singleplayer, bow for the pillars, mostly sword for the dragon. Pumpkin on the head.
Once in creative just so I could say I killed the EnderDragon with nothing but eggs.
