I remember playing the original demo of Doom on my 486-DX2 66mHz computer (my first PC), which had a staggering 4mb RAM, 420mb hard drive, 1mb memory graphics card and SoundBlaster 16 value soundcard. Ahh yes those were the days indeed and it was Doom that was one of the titles that made it a very memorable experience.
For those of us who adored Doom the first time around can rejoice now that it has been released on Xbox Live Arcade. It has obviously dated over the passage of time, but still with online deathmatch and co-operative play, it is surely worth a look?
