Some of the cards in Monty Python Fluxx have you performing songs or quotes from the movie, so it really pays to be nuts for Monty Python. The other Fluxx games don't seem to have such a strong dependency on knowing a certain subject well, so this is "hard Fluxx" in my opinion. It's still lots of fun, and I have had quite a bit of practice with my sparrow quotes and singing the Lumberjack song after playing a few games of this.
