PS1 - Final Fantasy 9
Just look at the sprite or the character model plus the eidolons model. Really detailed for a ps1 graphic.

PS2 - Valkyrie Profile 2 Silmeria
Nicely and breathtaking scenery especially once you have reached Valhalla.

PS2 - Final Fantasy 12
Just look at the characters model, really detailed. Another look at the espers. I often mistaken them for cgi.
