Correct me if I'm wrong, but for the PSN Plus...you don't actually own the game, correct?
I don't think I even realized this until I read an exert from Penny-Arcade: "[PlayStation] Plus is about paying for things you may or may not want. You pay for access to "free games" you dont own, or you're renting them I guess, and then if you stop paying your game turns back into a pumpkin."
So if you were to cancel your subscription, you wouldn't be able to access those games any longer? O_o
I'd just go with the Genesis Collection.
