Witcher's sex-scenes were to reflect his stud-y-ness, they were all repeated and re-skinned, and kinda hollywoody in terms of action (set design etc)
Cyberpunk's romances are much more story driven, and more creatively animated. There's only 4 in total, and 2 per player (since 2/4 love interests will be straight/gay, and therefore not be into you)
