Software Library: ZZT
ZZT is an ANSI character-based video game, created in 1991 by Tim Sweeney of Potomac Computer Systems which became Epic MegaGames in 1992. It remains a popular MS-DOS game creation system. ZZT itself is not an acronym for anything; its title was chosen so it would always appear at the bottom of newsgroup listings. It was later jokingly mentioned by Sweeney as being short for Zoo of Zero Tolerance, which has mistakenly become a popular belief.
