The only thing that signifies its the French release is the barcode, and lets be honest, nobody checks that.
Actually, I do. Because there are releases that sometimes look identical but in reality have different barcodes, so I always double-check.
Those are reprints I'm pretty sure if where talking ps2
but those have allot more things going for them. manuals and or box including a date way beyond their release date. discs having more lines of text. box art or manual having a slightly different color.
