I dont exactly understand why you would want to back off, if you think he liked you and you liked him. Are you saying you'd consider backing off to see if it [your absence] really affects him, like maybe he'd open up to you more?
It probably will affect him, though playing games isn't something many people will like. It might hurt him if he really liked you.
Its often considered that playing games will make people assert themselves toward you (since they feel they are losing you or you're becoming uninterested). Sometimes they will, or they might get discouraged.
I know that when I had done this, my girl just went crazy for seeing me after just two days...
You could try it, but you know, don't get habitual in playing games. Don't totally ignore him though. Would you like it if he did that to you?
