Let's see... I have:
Persona 2: Eternal Punishment
Both editions of Persona 3 which aren't really that rare unless you're looking for a new copy.
Shin Megami Tensei: Nocturne
Both Digital Devil Sagas
Koudelka
Disaster Report
Metal Gear Solid: Ghost Babel
Silent Hill
Xenogears
And I never realized it was all that rare, but my copy of Metal Gear Solid: The Twin Snakes died last week and it's not easy to find a new copy.
