There are many that are specialized for different uses in games, such as:

- ZZT-OOP

- MegaZeux Robotic

- ZIL

- MESH:Hero

- Free Hero Mesh

- Super ZZ Zero

- OHRRPGCE HamsterSpeak

(There are probably a lot more that I had missed)

All of these are specific to the specific kind of games being made with them, though; different kind of games will require a different kind of logic.

MESH:Hero is specific to a specific kind of puzzle games, and Free Hero Mesh is a FOSS clone of MESH:Hero with a different syntax and more features.
