Now I know that's the European boxart, but look at the bottom-left. It says it's not able to be played on any Mattel or NES Nintendo Entertainment Systems. Er...what? Now I'll give Europe the benefit of the doubt, seeing as I don't think Mattel released its own version of NES there anyway, but why didn't it say "North American" or "NTSC" instead of NES? Quite confusing.
