I liked this dating sim a lot. They use some of the narrative techniques you find in japanese dating sims in order to bring the reader something really special.
You have the option to pursue men or women and the game is formatted in a way that it doesn't matter whether the player is male or female. So you can play it gay or straight- the choice is yours.
The shining part is the characters and how you interact with them. It doesn't quite feel like a dating sim so much as just getting to know other (alien) cultures and civilizations. The people you have the option of ending up with feel varied and unique.
I certainly recommend giving this one a try.
