If you want PS2 games just go buy a Playstation 2 and sell the PS4. A used console is around $50 and install a hard drive with Mcboot tutorial on youtube. When the new PS4 comes out at e3 you'll be ahead of the curve. :)
Almost $50 for a nearly 2 year old game is ridiculous in my opinion nex gen or not unless it's a huge collector's item. I don't understand why people don't buy the used physical copies for usually less than a third of the price of a digital copy and know it will be in their collection without worrying something happen to a hard drive failing and/or console failing.
