I don't even know how much time I spent on IRC (dalnet) and when I discovered my local ISP had a Quake server it was huge!
We used to play Duke Nukem or Doom 1 vs 1 via a direct dialup connection, but playing agains 20 other guys on a Quakeworld server was just something else. The server was so badly run that every now and then something would happen to it that we used to be able to outrun our own rockets. I shot myself in the back with my own rockets many, many times.
I don't know how I even managed to graduate from high school really.
Hah, this. I thought it was pure magic being able to play Doom with a person not the the same room/house (we had a LAN setup for playing against people in different rooms), but it was so laggy.
And Quake/QuakeWorld.
