Wouldn't it be possible to save space using the zip bomb structure?

I may very well be misunderstanding something hard here but wouldn't it be possible to save space using the zip bomb structure?

Using a game as an example, if you aren't interested in playing a game with a very large folder size but don't want to delete it because of long download times, couldn't compressing the game in a zip bomb like manner minimize the occupied space, at least for games that don't consist of one very large file?
