hmmmm. I guess my favorite JRPGs are:

Shadow Hearts
Shadow Hearts Covenant
Final Fantasy XII
Crisis Core FFVII
Star Ocean TSS

In no particular order. If I had to choose the overall favorite, it would probably FFXII based on fun factor. I dug Shadow Hearts' story more though.

I stopped playing the FF series after I got about 95% through FF X-2... partly due to no more time avail. Although I have been playing Disgaea... hehe.

One RPG I wish I could play is Agarest Senki... too bad that's never going to come to the US probably due to it's mating system. Although the PS3 themes are AWSOME... :-D

favs so far are as follows:
Luminous Arc (NDS)
Disgaea (PS2/3)
FF7 (of course...)
almost everything made by Square (except Mystic Quest, FF8, and FFXI) no flames please.
Star Ocean SS
etc..

I also likes Lunar, Vandal Hearts, Evolution (dreamcast)...
