I was wondering if you buy the games with a credit card or can you buy gift cards to use instead, kind of like with itunes gift card and microsoft points for xbox 360…
Hi there,
To buy games you simply use your credit card or gift cards much like the other user said.
At this point we don’t know whether they will have a points system in place for the mini applications that they’re making available for the PSP Go (much like the iPhone). However I presume they’ll just keep it simple and rake regular payment methods.
Once purchased they are attached to your account and you can download them to your PC and then use the PSP Go manager application to transfer the game across to your handheld.

yah you can use credit card or gift cards
u just need to create an account and buy the cards or put your credit card info.. if u go to your account on playstation network it should be there all the info that u need with the cards
