I'm surprised seeing someone mention Chaos Seed, let alone put it in a top25 list...good guy.

EDIT:
I'll cook up a top25 list too since you enjoy looking at these, but I have to warn you there's stuff many won't consider "pure" RPGs:
-----
Brandish 3: spirit of Balcan
Brandish
Brandish 2: The Planet Buster
(It should be noted that I play those three games on PC-98 and I absolutley despise the console versions)
King's Field III
King's Field IV
Demon's Souls
Shadow Tower Abyss
Ys Book I & II
Ys Oath of Felghana
Ys IV: The Dawn of Ys
Xanadu
Xanadu Next
Sorcerian
Emerald Dragon
Brightis
Suikoden
Suikoden II
Suikoden V
Xenogears
Final Fantasy VI
Final Fantasy V
Final Fantasy IX
Shadow Hearts
Shadow Hearts II
Landstalker
-----
That list may seem outlandish to some, but that's how I roll

The order is a bit of a mess - I'm not even entirely sure if that's my preferred order...oh well.
