Title says most of it. All ages or 18+ is fine. Some others I'vee reallyliked have been Katawa Shoujo, The Fruit of Grisaia, and Maji de Watashi Koishinasai. More than anything for the amount of options and choices in each of them. I've been recommended Osananajimi wa Daitouryou, so I'll probably have picked that up before too much longer. Can't really say much else except that I'm just a sucker for a good love story.
