Also, there were multiple tournament websites out there: ESL and another one I don't remember the name anymore, that hosted tournaments all time.
I remember lan tournaments in Italy with more than 60+ Counter Strike teams like Smau 2002, and you had to bring your own computer nonetheless.
It was really a golden age for gaming I swear.
People that didn't live that think that gaming is better now are severely mistaken.
Playing online videogames today is a solo experience, 20+ years ago it was the very opposite, even if you played alone you met people on the same hosted servers you liked, on forums, on IRC, in lan.
