Nope, not yet. Yerr, if you've played FE3 there's hardly any point, especially since FE3 has Book 2 on top of that, though the shiness of it all is pretty nice, and the later introduced series features included.
Yep, more balancing and more Holy Weapon usage to use would also be w1n, I tried playing FEBinary Patch which has quite interesting features, but playing around it being in Chinese got too annoying.
I've actually played at least the first chapter of every game, FE2 was too confusing with the skirmishes, kind of like FE8, but a lot harder to work.
Remake would be sweet. Seeing all the characters, and huge maps in 3D would be awesome. FE5 is definitely the most difficult in the series. For being a Lord, Leaf wasn't that great. :/ I was actually playing FE2 not too long ago before I got distracted by something else. You can actually walk around and explore towns in that one, lol.
Too true, I've also played FE5, but haven't exactly finished it yet, way too intricate.
But the children system is awesome in FE4, definitely adds replay value, the only thing I hate is my need for Pursuit, limits some otherwise awesome pairings. Hopefully we get a remake some day. :D
