Girls are dumb. Why play games? If you want to talk to the guy, talk to him. If you wait and take a bunch of time, that's just being rude, it's not "playing a game." You don't do that on the phone or in person do you? So why do it with texting. And as far as you "just doing what the guy does," that doesn't make any sense. What if the guy is busy when you text him? What if he's at work, or at a movie with some friends, or hanging out with the family? Girls always play stupid games which is stupid. You're not going to make you want him more. You're either going to piss him off, or give him the impression that you don't like him. If you want a guy to like you, flirt with him and show him that you're interested.
But stop making up these stupid rules and stupid games that you "think" make guys want you more, but really just show that you're rude and insensitive, and usually just make the guy think you're not interested, and move on to a girl who doesn't play games.
