Yes, you will get the code via email. It will be sent to the email address you use as your PSN login. And the code is only good for the specified games (you cannot choose any others).
Everyone thinks I'm psychotic (except my friends deep inside the earth).
I haven't got the PSP Go yet but I was wondering if I sign up now with a new account, will I get the code? Or do I have to enter the information on the system itself. When I get it I don't wanna wait at least a week.
