I don't blame you. For retail games, I feel the same.I dont use or have playstation plus, Im not confortable with that "renting" method for the games ,i prefer retail games when the game is over 1g. and it gives me some sense of real property. Not that ps plus is anything bad , at the contrary , is great , just not for me.
In fact, when NGS+ came to PS+ for North America, I just went out and bought a physical copy. And pretty much everything else I've already owned. (I have tons of Vita retail games, Sonic Racing included.)
