In the interest of keeping it to games that are more likely to be new recs for folks... I'd say In Stars and Time, OneShot, Radiant Historia, Lost Odyssey, and Mice Tea (18+)

For manga, Even if it was just Once I Regret it, Yuri Story About a Girl Who Insists "It's Impossible For Two Girls to Get Together" Completely Falling in 100 Days, Can't Defy the Lonely Girl, Beauty and the Beast Girl, A Monster Wants to Eat Me, and Failed Princesses

Hope you enjoy~! ❤️
