"low hanging fruit" really, there are one or two that really try, but 99% are really just a 30 1-minute gen images put in a renpy visual novel style. There are few where is an actual dev trying to do something real and just not having the artistic workforce to back him/her up.
Yeah some of the Twinery ones do some really cool shit I would like a play around with at some point. As in the ones that implement a full phone OS operating systems and work a story around it. Just a shame the genre is NTR 😞
