I'm a big fan of the original and have been playing this remake since I got it a few days ago. I'm about half done with the game, and it rocks. It's almost everything that a remake should be. Sadly, it's a bit easier than the original, and that was NOT a difficult game, but almost all of the changes and additions are very welcome. Battle animation is still crap, but it's much better than before. They redid every song and they are all so much better than the shitty garbled synth the Genny forced us to endure. The graphics are clean and colorful, even moreso than before. There's loads of new content, from gameplay to story to player characters, even a few new missions thrown about in between chapters.
EXCELLENT game.
Still not quite as good as Fire Emblem, but it's more RPG and less Strategy, imho, so the two are NOT mutually exclusive. Go get.
Oh, another addition is the New Game+ when you beat it. You keep all the cards you found (which is nice, because I wouldn't want to find them again) but beefs up the difficulty a smidge. A nice touch, the more you beat the game, the more you can New Game+ the same file, making it harder, and harder, and harder...
