I've been told, online gaming (ps3) only possible with original discs...but like you said odez, with the internetconnection I have here, I even haven't tried doing it.
price (ps3) is a bit dependable on how big the memory of the internal harddisc is...mine is 320GB and paid 3,5jt for it, already able to play copies either from the internal memory or external memory, some games need to be loaded using the 'fishing' method (insert blueraydisc)...
copy's of PS3 games not available on discs, but need to be uploaded to either the internal memory, or ofcourse an external memory.
by the way, I pay 30K rupiah for ps3 games..
