If you have a lot of content to preload, this gives your visitors something to do while they wait. Its a simple little game that they can play while the content loads. - By editing the movie clips, you can simply replace aliens and other visual elements with some of your own (client products dropping instead of aliens, balloons etc.) - Entire game/preloader is in a single movie clip. All you have to do is copy the whole_game movie clip to the first frame of your FLA's main timeline. No code adding is needed, not even a stop() to the first frame. Just drag and drop :) - The game will adjust to the width of the flash movie you are preloading (using Stage.width and Stage.height), so no need for adjusting dimensions
