Tengai Makyo:Ziria for the PC-Engine was a fabulous game, really huge by 1989 standards, and then Tengai II:Manjimaru blew it away in terms of size and graphics (but not story). Both games have a strong sense of time and place and are amongst my favorite RPG experiences. I was disappointed that the PS2 remake didn't really go far enough in the updating department, but it would still be a worthwhile experience in English.
