[quote name='TylDurden']Technically gamesharing has always been against Sony policy. If you get burned they won't help and now CCs are only working on a limited number of accounts. Stuff like that. As far as the number of shares goes it's 5 PSPs and 5 PS3s per account.[/QUOTE]
That's correct... Game sharing is a byproduct of what-if-I-have-more-than-one-PS3s-or-PSPs.
Technically, it's a backup plan for the user in case his/her PS3/PSP is damaged, so he/she can register the account on a new PS3/PSP. A lot of time people don't realize that they didn't de-activate their account on the PS3s/PSPs when they trade them away.
But yeah, Sony don't need to be generous, they can just disable the "sharing" aspect easily. Translation, you can attach your account to FIVE PS3s, but any other accounts other than yours on the FIVE PS3s CANNOT play games not purchased by you.
Like the PSP... You can only attach to one account at a time... If Sony do this to the PS3s, heehee, bye bye game sharing (unless you like to de-activate and reactivate an account every time you're switching an account).
