ive recently joined the playstation plus. its gave me half a dozen games for the vita. so i downloaded them to the ps3. they are sitting in wee bubbles on the dashboard. i cant seem to transfer them to the vita. when i sign in to the plus account i can see i have bought them. so do i need to download them straight to the vita instead of the ps3? this is my first experience of downloadable games etc. any advice would be great.
