I remember seeing this very preview in EGM when it arrived in my mailbox.
I always wondered what happened to Final Fantasy Adventure 2, long after I got Secret of Mana, never realizing SoM *was* FFA2. I didn't find out until maybe 7 or 8 years ago, and yes I know now that the original Final Fantasy Adventure, aka Seiken Densetsu, was on the Game Boy and that Secret of Mana is Seiken Densetsu 2.
And Seiken Densetsu 3 (unofficially Secret of Mana 2) on Super Famicom is probably the best game in the series. I'm glad it was fan translated long ago so those of us who cannot read Japanese can enjoy it.
