Minecraft is the second most successful video game of all time behind Tetris. It was created by Markus Persson and has sold over 121 million copies across all platforms, making it the biggest selling PC game. Minecraft is a sandbox game where players explore, mine, and build in a virtual Lego-like world. It was initially self-published but its popularity led to releases on multiple platforms and its acquisition by Microsoft for $2.5 billion. Minecraft's simple yet engaging gameplay and ability to reach audiences across platforms through digital distribution has led to its commercial success on a global scale.
