I've heard nothing but great things about PS+ and am jumping in with PS4, having gotten the bundle from Amazon that comes with a year. Now every PS4 is getting a 30 day trial and it seems most games include a week trial. Does anyone know if those smaller ones will tack on to an existing account, or would I be better served to burn those before activating my year? Figure might as well use the free ones too, right? Thanks in advance.
