Ikusa Megami Zero, Ikusa Megami Verita, Madou Koukaku, Kami no Rhapsody, and Fuukan no Grasesta.
IMZ actually has one of the best jrpg stories I've ever seen, and Madou Koukaku is a great conquest strategy game. Fuukan no Grasesta is an excellent example of what Eushully can do when it wants to, even now. Too bad one like Fuukan only comes out for every four iffy ones.
