From the introduction:
This is a Blade Runner hack for Trollbabe. You
need the original Trollbabe rules where you can
read about the basic game mechanics.
Tears in Rain is not a game
about re-enacting Blade Runner or repeating all
the cool stuff from the movie. That’s been done.
It’s about dealing with a situation, and exploring
that situation through your own Blade Runner
character. Feel free to invent new awesome
technology like the Voight-Kampff machine or
the Spinners, and give them new cool names
and functions. Help the humans. Or help the
Replicants. Or try to negotiate between them.
Fall in love. Have sex. Solve crimes.
