zzt
A ANSI Text Editor based game released in 1991 by Epic Megagames (specifically Tim Sweeny) supposedly standing for “Zoo of

Zero Tolerance.” Because of its charmingly simple game editor and programming system included within, it has gone on to have a cult following on the internet, with many “zzters” (many of whom teenagers with too much time on their hands) creating new game files.
