Ive had my PSV almost a year now and have yet to buy a game digital or physical and have 3 friends in the same situation. Reason?
PS+
Why buy games if I get them for free*
I think Sony are actually onto something making PS+ cross platform, I already had it with PS3 so for me PSV is just gravy.
Also... PS4 or XBONE? Hmm, it would seem my PS+ works on PS4... I'll have a PS4 please.
