Gamasutra is an awesome site, and some very interesting articles. It was a good read. Other excellent RPGs that didn't make the list (SO2, Tales, Suikoden III) did get a mention somewhere or another.

FFIX didn't really excel at anything and wasn't particularly groundbreaking or unique in any way, nor was it supposed to, as it was a nostalgic collaboration of previous Final Fantasy titles. It was done in a fashion to accommodate its style in a three dimensional universe, as to combine the past and present of RPGs. Even for such a restricted gameplay device, it wasn't executed perfectly. So, there's no reason that a game like that should be on an Essential RPGs list.
