... because that was the most impactful for me personally. But after reading all the other responses I think I'd agree with those saying the PS1. It's the console that really brought "GAMING" more into the mainstream and less as a niche thing for kids. I remember being blown away that my high school math teacher had the PS1 AND played Magic: The Gathering.

I think the console didn't resonate with me though because I got one waaaaay late in its cycle... i think right before the PS2 came out.
