All the programmers at my dads company played this in the early 90s til some Melvin played it with the sound on and got everyone busted.
can't tell you how many times alt+tab saved me from getting caught playing it in our computer class in 7th grade.
best comp gaming outside of oregon trail was when someone got into our HS's server and put mario kart and halo on there and you could play with your friends in any classroom in the school god damn that was awesome
