My 2 cents. We know the game will have straight and gay romance, that is already leagues ahead of most games. That being said I am far more interested in the story and combat and character development than what characters look like. If you want "hot" characters play a dating sim. I for one want thank the devs at Spiders for their hard work and I eagerly await further news
