CS Source for me became the very first and full-fledged CS that I met and to which I got used.
At that time it was a real breakthrough - Contra on a new engine, with support for shaders, Ragdoll physics, and just ordinary physics. It was something.
KS pulled me into many hours of real time. Here you could find a server where after school you could go in and relax, chat with dudes, men about anything.. It’s not like now, if you’re not a student, it’s a biomass of sheer aggression.. Before, everything was simpler.. Ks on source, and the grass is greener.
