well i suppose we should start from where there are most of these
https://monarpg.usamimi.info/
most of these games require rpgmaker 2000 rtp and your locale set to japanese in order to play them (probably better if you go with easy RPG for some).
most of these are mostly traditional RPG'S but there are some that try to be different in gameplay somewhat, i do recall having seen one where it's akin to resident evil, but i am not much sure what was the name off.

i love the engrish in some of the names.
