So far there are two dating sims for girls in English.
The first is Animamundi and the second is called Enzai.
The company that released Animamundi is called Hirameki (google it), they're going to release a new game for girls too, called Yojinbo soon. And they're planning to release another one called Princess Nightmare next. Enzai was released by Peach princess. It's a male+male game (yaoi)
