I know similar sentiments have already been expressed, but...

Calling it a "porno game" seems wrong - that could really only be right if literally everything with a depiction of sex is "porno". It has a couple of sex scenes. At least, someone playing Fate/Stay Night looking for porn will be sorely disappointed.

(And the way the "Creating a physical link between Shirou and Saber" scene was handled in the anime, I think I'd rather it were the sex scene from the visual novel, despite my generally disliking sex scenes.)
