It's pretty simple: If you want to play a very high quality AVN, that is sensibly, very well written, by adults to adults, you should play it.
Leaving DNA is just all around great, from the LI's to the graphics, story, everything is really fucking good.
Take the warning at the start seriously, as the game does tackle serious topics such as sexual assault and murder, but the author does a magnificent job in not letting these heavy topics bring the mood of the story down.
Everything is really well balanced and works really well, and if you like the first 20 minutes of play, you will enjoy the rest, given that Impious Monk seem to have a well thought and structured story already planned, and so far the consistency between chapters is very strong.
TLDR: Serious game, real fucking good. If you are looking for a good story with adult elements, you should play it.
Also, Jamie is an incredible LI, all around 10/10.
