I haven't tried the other two since they aren't Ren'Py, so hopefully they keep up with this one! I've wanted to try the other two you mentioned.
You're missing something then. Even though I hate RPG games, My Sister Mia (renamed Living with Mia due to Patreon) is hot and has some amazing scenes. Plus, it is really funny. It's not perfect, and there are some annoying mini-games that cannot be avoided, but the overall story is amazing, and the animations are super hot.
EDIT: And for clarification, I am
not a RPG, Unity, RPGM, or other platform fan. I can count on one hand games that I have played on those platforms that I actually liked (Mike Masters' College Life being another one of them). Usually when I see a game is in a platform other than Ren'py, my inclination is to move on to the next game.
