I recently was given a promo code to redeem a game on my PS4, and before redeeming it, I checked my library and noticed that the game I was about to redeem was already listed there. I can't remember if the game was one that I purchased, or downloaded for free through my PS+ subscription.
Is there any way to tell, on the console itself, if a game in the PS4 library was downloaded for free through PS+? Or is the only way to look through one's purchase history online and pick out the ones that cost nothing?
I ask because if the game is from my PS+ subscription, I'd like to still redeem the code, as I would like the game to be available after my subscription has expired. Otherwise, I'll hold off on redeeming the key.
