So I was browsing the Playstation Store on my PS Vita and I noticed it said free next to Playstation All Stars Battle Royale. I was confused about this since I had only bought a hard copy for the PS3 and the game was not being given away. Next to the game it showed the red Playstation bag saying I already purchased this. Does this mean I can play games I own on the Playstation 3 for free on the PS Vita regardless of it being a hard copy? My sister bought Project Diva for the PS3, but that's not showing up as a free download on the PS Vita version.
