Alas, I played all three in the early 90's. lol
They are worth the look if you haven't played them. The writing is highly arousing, which is good considering the 2D ancientness of the graphic's. But for its time these were the state of the art in e-hentai. Glad you included them in your list. It shows refined tastes and knowledge of the genre.
I love tentacles, rape, and sickness in a completely fictional cartoon setting where no one really actually suffers. Being able to interact virtually is a plus all around. Makes real life's monotony, that much more bearable.
If you're a guy, and never had a rape fantasy, you're likely too effeminate, so refrain from commentary on a topic/game obviously for 100% Viking style men. I would call you a latent homosexual, but even some queer men are rapists. You wussies...
