here's a comprehensive list of US-released RPGs:
Albert Odyssey
Blazing Heroes (also released first as Mystaria, it's the same game)
Dark Savior
Dragon Force
The Legend of Oasis
Magic Knight Rayearth
Panzer Dragoon Saga
Shining Force III
Shining the Holy Ark
Shining Wisdom
Virtual Hydlide
all of those are excellent, except for Virtual Hydlide, which is pretty much unplayable. Blazing Heroes/Mystaria is tolerable, but nothing super special.
the US version of Shining Force III is actually SFIII: Scenario 1. the other two scenarios were released in japan, and i THINK both of them have been translation-patched, but i could be wrong. I know Scenario 2 got finished. but, really, as far as translation patches go, that's about all that's available for the poor saturn.
as for good Japanese RPGs (you can find translation guides on GameFAQs, typically), these are some of my personal favorites in terms of presentation/ease of understanding:
Tengai Makyou IV: The Apocalypse
Princess Crown (predecessor to Odin Sphere/Muramasa, great title)
Shiroki Majo: Eiyuu Densetsu (Legend of Heroes 3)
Wachenroder
Arcana Strikes
Grandia
Black/Matrix
Devicereign
Madou Monogatari
Terra Phantastica
the saturn is an excellent system full of amazing titles. it's also hella expensive to collect for, so if you're planning on acquiring some of the best games quickly, be prepared. i used to collect for the saturn, and when i finally gave up on it and sold my collection, i made a pretty penny, but i don't think i'll ever get to the level that i was at ever again. *sigh*
