I always find it hilarious when the game clearly is about mom / sister incest, with not even a thinly veiled attempt at hiding that on the dialogues, but it lets you name what the characters are to you. I tried to name his "mom" Bitchy, and say she was my Cousin, third degree, but ended up with her being "his bitchy".
"you leave your bedroom in order to meet your younger Cousin, fourth degree, but as you get out you see your Bitchy outside her room."
The whole thing is hilarious, and not in a bad way; the main character gets mocked for going into Chemistry rather than Programming and told "You couldn't handle the pressure and you just ran" as if programming was well known for being something people get afraid off, over Organic Chemistry.
Another interaction for which I am thankful they didn't limit the characters for the family's title:
"Are you getting excited at looking at your older Cousin, fourth degree in a dress?"
Did anybody else play with that, or just me?
