Maybe he was playing on 1.0.6?I can't think of anything for myself, but for the longest time, my brother didn't know about hardmode. He thought he was so great at the game, he had meteor and hellstone armor, a drax(you could get those from shadow chests back then). When he showed me the game, I thought it was the best thing ever. I started watching a bunch of Terraria stuff on youtube, and something mentioned hardmode. I looked it up, then told my brother that he was basically missing half the game.
