Apparently some of them are very good in their own right, telling a compelling and interesting story and not just being horny cash-grabs so I’m tempted to give them a shot.
I played the original Yu-No because of how it is the foundation upon which all modern visual novel games are built. That was a difficult experience and I do not recommend it to anyone not already very interested in the history of the genre, there is a lot of content there that is not for me.
But that was the game that made the industry say “oh shit, these things can be good, too”.

Side-note: the modern rerelease of Yu-No has the more objectionable stuff stripped out, but then we’ve got to have the censorship discussion all over again.

Anyway. My point is this: I have also overlooked these games but might have to rethink that.
