I think Atari is a bit overrated in these discussions. First doesn't always really matter a lot-- Atari was the first but I feel NES was the first that really drove home the proof of concept and Atari offerings were failed experiments in expanding arcade gaming to homes as much as anything. Was it influential? Sure. More than Microsoft or even Sega? Honestly don't think so.
No problem!
This is a cute and pop genocide of love!
