So let me get this straight:
Japan released SMB2 (Lost Levels)‚ they also released Doki Doki Panic. Then they slapped Mario characters onto Doki Doki Panic and sent it over here to the States and called it SMB2.
But then someone decided to release the repackaged U.S. version in Japan. So they essentially released the same game twice, on the same console? Wow.
