Do you play computer games? If you do, you’ve probably played Minecraft. When Minecraft creator Markus Persson was young, he wasn’t very interested in the games themselves. He was more interested in the programing instructions in the computer’s manual. By the time Persson was eight years old, he was writing code for his own computer games. When he was eighteen, Persson landed his dream job as a video game programmer. In 2009, he designed Minecraft in a single weekend. In the game, players use blocks to build whatever they choose. Persson wanted to let players use their imaginations, and the idea paid off. Today, Minecraft is one of the most popular computer games in the world. Although Persson doubts he will ever top this success, he continues to develop games, while fans wait for what’s next.
