Do I lose access to games I've downloaded when they're removed from the Instant Game Collection?
If I download a game from the Instant Game Collection, and it is later removed from it, can I still access it? Do I keep it till I delete it or unsubscribe?
PS Plus seems like a great deal but it would suck if I lose access to games I am only halfway through.
You'll still have access to the games you've downloaded, even if they're removed from the collection or you've deleted them off your system, as long as you're still a subscriber.
If your subscription ends, you won't be able to access those games, but they'll still be available again if/when you resubscribe.
