I would not say wrong but I do see your point as well. It all depends on the game you are making as to how much you reveal, it relates directly to Step 10. It is all about addiction, if you can get someone hooked in 10 seconds...make a 10 second demo, if it takes 20 levels...make a 20 level demo. Its a fine line and you have to know where to draw it. Edit: Awesome article... how did I forget that.
