As a kid I was always under the impression that the N64 and gamecube were as popular as the playstation consoles. I knew at least 3 different friends that owned a gamecube and N64 along with a playstation 1,2 console. Also met some people who said they owned them.
I always heard people talk about them and I would see the games and magazines like Nintendo power in the stores. So I thought they were very popular back in the day.
You can Imagine my surprise when I got on the internet years later and discovered the sales numbers for those consoles.
