Actually, the PS3 is region locked. Most games aren't, though.

 

Really? I was sure the PS3 was 100% region free =/ Which games are region locked on the PS3? And if they are region free then what's the point of PAL games then (besides the ones that are region locked) on the PS3?

@Everyone else

Hmm...that makes sense.

Not sure, 99% of all PS3 games are probably region free. But yeah, the PS3 is indeed region-locked. It probably has something to do with it's DVD playback capabilities. I think you also can't play NTSC PS2 games on a PAL PS3.

The PS3 has a region lock on certain games that are incompatible if played in SDTV. Region lock is nonexistent if played in HDTV.
