Really? KH1 had an original Japanese version, then an updated NA one, then a FM. People still bought all three because each of them are different.
KH2 was different in that stuff was the same between the JAP and NA version. Then they made KH2FM+.
But BBS is different in each version like KH1. So really, I don't see the pirating as being justified considering each game has a different serial number and the fact one came from the Japanese market and the other from the American market. Two different systems, which means your pirating is still illegal.
Only in the case of owning the certain countries version would you be able to pirate the same version from the same country.
And BBSFM is a different version. So it is still illegal.
Maybe I just have a rage thing about people pirating video games. I don't care about movies and music and shows, but games are a different thing to me.
