RELATED: The Best Video Games for Kids Under the Age of 10 The experiment in this instance has to do with Baio’s obsession with video games. When his son Eliot was 4-years-old, Baio bought him the original Pac Man. Starting there, they worked through the Atari 2600 classics before moving to Nintendo NES, then the Nintendo 64 and so on. By the time he was 10, Eliot was already up to the present day, and he’s developed two interesting traits: First, he has a surprisingly sophisticated appreciation for game theory. Second, he’s ridiculously good – so good that the creator of an infamous game called Spelunky believes he’s the youngest person to ever complete the game in it’s dreaded “Hell” mode. Maybe, for his next experiment, Baio can try to design a game his son can’t beat him at.
