Take the 2-minute tour ×  I'm looking to expand my game system
library, and I would like to tap the hive mind to find funky,
offbeat core rules or settings.  What system should I add to my
game library that best features novel rules that actually work
in play?  Guilty pleasures are welcome, but I want to know why
it has a place in your heart; actual play reporting is
encouraged.  If it's out of print and/or produced by an
independent game publisher, I'm interested. But I need you to
tell me why it appeals to you. If you have any links to a or
site detailing your experiences with your system, please feel
free to post that in your answer.  Example Answer: I enjoyed
playing Psi World back in the '80s because the idea of an
underground resistance movement in America started by people
with emerging psionic powers is just cool. Yes, it's a premise
detailed in X-Men, but Psi World accomplishes the same paranoia
feeling in a much grittier way without so much spandex.
