So, there's a whole lot actually, can't recommend too much
Monster Girl Quest the gameplay is pretty simple, but the story is good and there is a improbable number of girls to H (You have to be in femdom tho, because 95% of the H scenes come from losing) similary, you have
Paradox the sequel to MGQ, that one being a rpg maker game, with teammate and the like.
For the rest, when you talk about rpg with a lot of girls, you have :
Eiyuu Senki if you like strategy.
Rance Series who is a pretty much an obligatory when we talk about long running series and h-rpg.
Renryuu Ascension if you like rpg with a lot of variety when it comes to what you can do.
The Last Sovereign if you need something more mature in your life (less girls in this one tho, and text based when it come to the H scene).
I have to add, for me, all those above have a story or gameplay ranging from "cool" to "even without the H, that's a pretty fucking good game on it's own" So, try it if you want to !
