There was bit of a perfect storm for me when this game came out. I was working part-time in EB then and got to loan this out (they used to have store loans for store performing well, or not badly) as it arrived in (just before release).
This was on a very new; Gateway Pentium 2 450Mhz, 10.2GB HDD, ATI 8MB card (can't remember specific model), 128MB Ram, LS-120 superdrive, 19" Monitor and a Diamond Orchard Voodoo2 12MB 3dfx card (bought from EB).
I remember waxing lyrical about the game to my then colleagues.
Note this computer went through a 3dfx 2000 and Geforce 2 MX that both handled TFC and DOD for years. Then August 2001 I finally upgraded to a Athlon 1800XP.
Awesome game and remember parts of it like it was yesterday. Still yet to play Black Mesa. And spent countless hours on the MP mods; TFC, CS b3.0, DoD (my fave with TFC), Action HL. Remember it was incredibly difficult tracking down Opp Force expansion on the release day, because no-one had it in. Bought it in a high-street electrical store of all places.
