There is one other SNK RPG like game out there, KoF Kyo, released on the PS1, plus Athena has had a few side games, though I don't think any of them are RPG's. I am a fan of Athena, both Goddess, and ancestor, and surprisingly, outside of Athena on NES (I need to get that on PSN, the arcade version), all the 2D KoF's and Psycho Soldier on PSN, I have none of her offshoot games.
