I'm wondering if I can buy a downloadable game while in the US and continue playing it when in Canada?
Edit: Also, is it possible to buy the game on a machine in the US and re-download it on another machine in Canada?
If you have a canada psn account you can play what ever you buy on that account in any country.
if you have a US psn account you wont be able to download games from Canada.
Basically if the account you download the content from is on the PS3 you can play it no matter where you are as long as the system is active on that account. Remember only 2 systems are allowed to be active on one account.
hope this helps
