I remember the times when playing a multiplayer game was not very easy.
During the times that DOS was the dominant home OS, most multiplayer sessions invlolved a serial cable and taking a PC to the place the gaming took part at.
If you were lucky enough to have access to a LAN populated by other willing players, you were one happy camper.
I already tried out Death Rally and it worked like a charm.
Now I need to test drive Doom, Duke Nukem 3D, Mechwarrior 2 :)
