Wasn't really into the first game, was more into WC2 around that time as a mate and I use to play over dial up and he was really into making custom maps, which added a lot.
I went through a phase when I tried making a bunch of maps in StarEdit. Came up with some fairly good ones, and had some fun with scripting the triggered events. Unfortunately I never quite figured out how to make the AI work as well as it does in the normal game.
