Yes you will, free games are only available to you while you have a vaild subscription.
Free avatars & themes are yours to keep though, as are any games you put any money towards.
I just wanted to add that you will get access back to those free games, should you decide to renew your subscription in the future...
What if I get PS+ with another account, do you know if I can play the free games I got with the first one?
Account 1 gets PS+ and downloads free games.
Account 1 PS+ expires.
Account 2 gets PS+.
Can account 2 play free games downloaded with Account 1?
I can't seem to get a final answer, I saw that the downloadable games for this month on playstation plus is the 2 psone castlevania games. I haven't bought a subscription yet to playstation plus, but I saw if you are a member you get both those games for free. My question is since they are from the store and technically being bought(even though ps+ get them for free) after the subscription ends if I decide to do the 3 month will I be able to play those games? Or are they definitely not playable unless I keep renewing the membership? It seems like all the statements I'm reading is the demos and full game trials will not be able to be played once the membership is cancelled or expires not the ones I would "buy(download for free" from the market.
