Eh, how long has looney tunes and Bugs Bunny been around? I was watching that with my silent generation grandfather into the 2000s, and my first video games were basically my Gen X dad's first video games on the 2600 and first Nintendo, Intellivision. I think the simplicity of those games and that IP is just universally approachable for people at a certain age. Before Pokemon cards, it was just sports cards for ages.
