You get awesome infinite ammo guns, you can go through the campaign in a straightforward way, generous fast travel, intense car chases. A pure experience.
First GOG users are like "enough with these pron games!". Then they are like "why you censoring?" If the developers have decided to censor the game, good for them. Could offer an unofficial official adult patch in the forums, that would be a nice option. We have to respect the creators' intentions even if we don't agree their direction. I myself don't necessarily need nudity to enjoy a nice creepy story.
