Really? So I can literally just DL every game and delete it right after installing and play it a year later as long as i did that previously? that is pretty freaking great.
You don't even have to take the time for an initial download if you're just going to delete it. Just checkout through the PS Store web site. You can even run PS4 content through the cart if you don't have one. When you do, all that stuff will be in your purchase history.
