In the late 80’s, I wrote two video games.  The first was called Zenix and was released in 1989.  The second was called The Crystal City, and was released in 1990.  Zenix was one of the most ambitious 128K Coco 3 games done, at least until the same author came out with The Crystal City a year later.”  See the review of The Crystal City.  Watch Madgun68 play the original version of Zenix.  Watch Marlinlee play the original version of the Crystal City.
