I just joined PS+ in November when I bought my PS4. I just got a Vita for Christmas as well.
My question is more so targeted towards Vita owners due to the limited space on my memory card (16 GB)... If I delete a game from my memory card and want to play it again 2-3 months from now, do I still have access to download it again from PSN since it would no longer be one of the free games for that month's instant game collection?
For most of the games I will probably be okay with just one play through... but I could see myself wanting to come back to Soul Sacrifice again and again.
