Yes PS3 games acctually work on ALL PS3's!
Fortunately, any ps3 game around the worlds can work on any ps3. This is not possible for blu-ray dvds though.
No, PS3s from the Western Hemisphere can only play games sold in the Western Hemisphere. If you try to play a game from the UK on a Playstation 3 in Canada you will receive an error message. This is also true of games bought in Japan, they cannot be played on PS3s from Canada.
