Ok, I agree it is very rude generalization to call visual novel a pron game... but technically it is :)

Prologue:
With all those talks about Jango Unchained I remembered original Django.
I love spaghetti westerns.
If you lived in USSR you would get A LOT of them since Deutsche Film AG made tons of movies in mood of spaghetti westerns.
With Gojko Mitić as "honorable Indian" - role model for kids and wet dream for women in USSR. Seriously check out his filmography someday. He is great and I wish I would look so great as he is in his eighties

And main attraction in this post.
I also remembered about one particular Japanese visual novel which is also related to Django - Tre Donne Crudeli

Five years ago I tried to play it... since I didn't know what to do (I don't speak Japanese) and save feature didn't work (my PC also doesn't speak Japanese) but I managed to play few minutes and surprise: Beginning is homage to beginning of "The Good, the Bad and the Ugly"

Not only this game awesomely drawn by great Niθ... Honest to God I've never heard such beautiful soundtrack in any adult media.
Here is my favorite.
