At first, the video game Tetris seems simple enough. When you really get into, though, you realize there’s a complexity to it that may be subtle, but it’s also substantial. Not surprisingly, the story of how Tetris came to be also seems simple enough at first, but not when you real dig in. It’s a story told in the new book The Tetris Effect: The Game That Hypnotized The World (hardcover, digital), written by CNET editor Dan Ackerman (who, I should point out, is someone I’ve known for years from going to video game press events). But in talking to him about his book, it seems it wasn’t just a love of the game that made him want to write something this substantial about Tetris.
