I'll answer this as legally as possible. In order to access your PSN games on another system, you must access your account on that system by logging into PSN, then re-download them under your account. I have read that some games, however, can't be shared. Hope this helps.
I see, thank you for answering my question as legally as possible and not giving an illegal answer because that's exactly what I didn't want. Thank you, I'm getting a hint that this kind of talk isn't allowed so I will look elsewhere.
Just an FYI... we have a lot of older threads on PSN gamesharing here but these days most of it is of no use and the few titles that can be shared up to 5 times are usually done in more private/trusted circles so that each user's PSN account info isn't compromised etc.
I have no problem if a bunch of users wanted to start a gamesharing group in the BST area (for Trading) but it would be at your own risk.
