commodoreZZT

ZZT was a game creation system designed by Tim Sweeny, founder of Epic Games (once Epic Megagames) and released as shareware in 1991. The game came with an editor that used its own custom coding language, ZZT-OOP, and users began to publish worlds on the fledgling AOL boards. ZZT's popularity continues into the 2000s, making it one of the oldest active Internet communities.  Epic released the registered version of the game as freeware. ZZT is not a musical duo, one half of which was responsible for stealing David Whitaker's Lazy Jones SID.
