CS:S or CS in general?
i got into source maybe a year and a half after it came out, i was still rocking 1.6 for quite a bit. I dont like playing games that my system cant run smoothly, and at the time my computer was lacking.
the first game that i bought after putting together a new system was half-life 2, and consequently CS:S, and it stuck with me.
i got into the original counterstrike around 1.3, I couldnt run UT, and games like Rainbow six just blew ass, particulary the multiplayer interface (i forget what the thing was called, it was web-based, i used to play AoE2 on it), this was also when my dad an I finaly got cable internet!
also 2 of my good buddies at the time were rocking counterstrike and got me to join in.
Counter-Strike gameplay mechanics attract me compared to every other FPS, although i havent played any of the recent Tom Clancy games, but their multiplayer is ass.
