The Elder Scrolls II: Daggerfall

[Skarro]

It was originally planned for the player to have sex with NPCs in the game, and there is plenty of unused NPC response text strings in the games code reflecting this. (The % sign seems to be some sort of text trigger)

Do want to make love with me?
Tell me you want me like I want you.
Do you want to fool around?
I'm yours if you want me.
Do you want to slip away and make love?
I don't want to talk. Let's make love.
Come on, sweetheart. Lets do it.
Would it offend you if I said I wanted you?
No more talk. I want you.
I want to hold your body tight against mine.
Don't you want to do something more than talk?
Kiss me, %pcf, I'm yours.
Hold my body against yours until the morning comes.
Let's do something we can be ashamed of.
Why don't you stop talking and kiss me.
%oth! Can't blame me for asking.
Oh. How embarrassing. Forget I asked.
I'm sorry. I thought you felt it too.
Well, maybe later.
Ah well, I can always dream.

Also the "Prostitutes" guild was originally joinable, and opened the following text strings.

Looking for a good time?
You want some company, honey?
Interested in some good, filthy fun?
For you, how about a freebie?
For old times sake, how about a freebie?
Time of your life, %a gold.
Special price, %a gold.
What'd you say to %a gold?
I ain't no charity, honey.
No money, no fun, sweetie.
