I just started playing
Now and Then. I don't remember where I got the recommendation, probably not here since it's only been mentioned 3 times in the past. Also, it has some elements that probably disqualifies it from the list, but I still needed to bring it up, because the writing is so damn good!
We have some real characters with reasonable motivations and believable development. We have good dialogue, and we have some really well executed thriller scenes (it's a zombie apocalypse story). It would pass the Bechdel test.
On the down side is that it is quite haremy and that the MC suffers from magical dick syndrome (every woman/girl wants to fuck him). I am also not a fan of this type of renders (Honey Select?), but the creator is really doing the most of it, especially when it comes to light and shadows.
Anyway, all those negatives could easily be forgiven just for the fact that it is so good. I'd say there are several TV shows running now that are inferior.
And did I mention that it is completed?
I am two thirds in, and I am really looking forward to actually being able to binge-read this all the way to the end.
