I think the only major change I would do with the Worst list is replace Ehrgiez with Tobal No. 1 and knock it to rank 2 while pushing All the Bravest to the number one slot because that piece of trout is barely a game and blatant cash grab of the worst kind.

Ehrgiez was hardly a good game, and if it didn't have the cameos from FFVII in it, I'm sure no one would have played it outside of Japan, but Tobal No.1 is easily the worst fighting game Square ever made, Ehrgiez at least had a few redeeming qualities but Tobal just sucked.

As for the Best list, I would replace KHII with either Chain of Memories or Birth by Sleep and then drop it towards the back. I've oddly enough, never played any of the Parasite Eve titles, and only know them by reputation, so I can't really comment on it. Though part of me is tempted to replace it with one of the SaGa titles instead. Course there is also Xenogears...
