As a gamer, I'm always amazed by how realistic the modern gaming experience is. I'm currently playing the latest God of War on the PS4, in stunning 4k resolution. I can't help thinking about how far we've come since the video games of my childhood. I vividly remember playing Adventure on my Atari 2600, where your character was represented by a small square able to move from room to room, picking up things that kind of looked like a key or a sword. Pretty amazing transformation since then.
