… has got to be sneaking into a computer lab at the University of Manitoba in highschool (around ’95 or ’96) with a couple of friends to play Warcraft II:Tides of Darkness over their IPX network.
The worst part was, because the machines were ghosted (or some archiac version of ghost) on boot up, we had to do a fresh install of the game everytime. Though this did do a great job of covering our tracks when we left.
