Not all, but a vast majority.
Some have region locked multiplayer also, like MGS4. You can play a a US copy on a PAL PS3, but when you try online you can't connect to the Euro servers, or the US servers. You can only connect to your own regions servers, and only with a copy of the game from your own region. |
I've never heard of lockouts, so I haven't thought that there were any. As for online, it's pretty expected.
