I have a modest amount of JRPGs. If I could list them, they include (by console):
PS3:
Final Fantasy XIII
Eternal Sonata
Star Ocean: The Last Hope International
Ar Tonelico Qoga: Knell ar Ciel
Resonance of Fate
Trinity Universe
Agarest War ZERO
PS2:
.hack//INFECTION
Final Fantasy X-2
Final Fantasy XII
Star Ocean: Till the End of Time
Valkyrie Profile 2: Silmeria
Xenosaga I, II, III
Tales of the Abyss
Kingdom Hearts II
PSP:
Valkyria Chronicles II
Phantasy Star Portable I, II
Persona 3 Portable
Crisis Core: Final Fantasy VII
Kingdom Hearts: Birth By Sleep
Nintendo:
Pokemon Sapphire, SoulSilver, Black I, Black 2
Legend of Zelda: Wind Waker
Tales of Symphonia
Summon Night: Twin Age
I've played every one of them for quite awhile to get a good impression and know them by heart. But to state whether I finish them entirely or not is a different story. My personal favorites are Tales of the Abyss, Eternal Sonata, and Xenosaga III. I had to list all the Nintendo ones because they were definitely a part of my childhood.
EDIT: Just wondering if visual novels count as well, they're more like dating sims than RPGs. If they are, then I've definitely read a fair share of them.
