too bad =/ it's definately a game for those who want to be creeped out... not just doom fans.... the actual minimum requirements are:

windows 2000
pentium IV @ 1.5 GHz or AMD Athalon XP1500
384 MB ram
2.2 GB for install (more for saves, but prolly less than 1 mb lol)
8x CD ROM drive
video card and sound card that supports direct x 9.0b (minimum video cards: ATI radeon 8500/NVida 3TI series)

not that steep by today's standards.... like isaid, back when it came out people had to rebuild their computers....
