This entry hails from Korean company Cheritz, whose dating sim style games have been appearing in English for several years now -- and as of last year, have managed to get two of their more popular offerings onto Steam through Greenlight.
The story in Nameless starts off as simply as the others - you play a woman who recently lost her grandfather, with whom she has grown up alone. An avid collector of ball-joint dolls, one night they suddenly come to life -- a group of incredibly good-looking, life-sized men.
Crazy, right? She thinks so too. Good writing and a relatable protagonist makes this story shine.
