[quote name='torifile']The 5 PS3 limit is
per game. If you bought SSHD, Pain and PJM, say, and share PJM with me, you'll still have 4 shares of SSHD and Pain and only 3 of PJM (as long as I didn't swipe Pain and SSHD without telling you!

I use different accounts to minimize this problem).
And your future game sharing is completely unaffected. So, if you bought Everyday Shooter after you've changed your password back, you'll have 4 shares left (after you download it, of course).
Does that clarify some?[/quote]
It's a 5 account limit not game limit. Although it sounds similar it is not. That's presumably why you create different accounts though so people don't snag your other stuff (BTW there's a 16 account limit per PS3).
To use the example above in your terminology

If you bought SSHD, Pain and PJM, say, and share PJM with me, you'll have lost 1 share out of 4 for all games.
EDIT: READ the OP. There's also one or two more old gameshare threads that prove this point also.
