Yeah, Was Doom for me too. On a Packard Bell 486 no less. I remember cause my dad set it up to be dos 6.0 with some sort of GUI and from there you could launch windows 3.11 for workgroups.
Yep, It was Doom, then Descent, then Descent 2. the next real big game was when I was selling fireworks in Washington (2002). I got the honor of beta testing the original version of Steam for a few days, in which I got to play Half Life. And I've been a Valve junkie ever since.
