ZZT's financial success allowed Tim Sweeney to continue funding game development and growing Epic into the major gaming company that it is today.

These worlds developed in complexity over time taking a language with seemingly limited functionality and allowing it to be used to create complex 'engines' such as producing procedurally generated dungeons, RPG battle systems, inventory based adventures, and even generating fractals.

Over the past thirty years people of all ages have created ZZT worlds thanks to the incredible accessibility of ZZT's editor and scripting language. On a surface level the language allows basic functionality to display text to have objects move and shoot to test basic conditions and most importantly for objects to send signals to other objects to jump to different labels in their code. The scripting language known as ZZT-OOP is notable for being incredibly simple to use, allowing people without programming backgrounds to create games. This editor allows players to create their own ZZT worlds utilizing numerous built in elements for items, creatures, terrain, and a scripting language that allows 'object' elements to be programmed. ZZT found success from its inclusion of a built-in editor available even to those who only had the shareware version of ZZT.
