It's a remake of FE3, the sequel to FE1. (FYI, FE3 came with a remake of FE1 but it still had a sequel in it).
And like I said you shouldn't judge it based on Shadow Dragon because a lot of the missteps they made there are fixed in it and they added a bunch of cool things people wanted like supports. Also, it was the game that introduced the concept of "My Unit".
There's a translation patch in progress for it fyi, and it's pretty much done. It's in beta testing now.
