IMO, it’s not the technology that matters but the authoring tools. Flash was easy to pirate, sometimes free with school, and easy to use. Thinking of applications as “animations with scripting” was a great idea because it let people only learn what they wanted to.

If you just want to make animations, skip actionscript entirely. If you want some extra Easter eggs, just turn any symbol into a button and you can trigger any movie clip you want. Want to make this a whole game, heres the whole action script editor.
