I'm sorry, but I can't agree with that. I have played TLP, Requiem, and this. Very little of EN is well-written. The script is full of colloquialisms, "told" exposition rather than "shown," characters who have completely lost their voice compared to FE7, juvenile diction, and the most spelling/grammar errors I've seen in an FE7 hack.
There are bits of writing that stand out in a good way, and Sain particularly has largely kept his voice from FE7. But otherwise, I had a very difficult time believing these characters are the same characters from FE7. Some of their motivations and characteristics have shifted in odd ways, and they make decisions that don't fit their personalities established in the main game.
Fun and creative hack overall, but Requiem has the best writing I've seen in a hack so far (by a decent lead), TLP would follow it, and then EN in a pretty distant third.
