Shadow Dragon is actually a remake omnibus of Fire Emblems 1 and 3. That's part of why the character depth is so shallow (FE1 and 3 were on the NES. There wasn't any room for support convos on there) and why it feels a little primitive. There have been additions to make up for it (A few new maps, graphical overhaul courtesy Hiroka Oku, The Weapons Triangle, and the Class Swap system), it's still basically just FE1 and 3 all over again.
Not like it matters to most people though, since FE1 and 3 are Japan only and this is a US release. Really, it's kinda like what Square did with FFIII a while back.
