Few people know that usually more can be gained in a pre-contract negotiation than in negotiations after a written contract is supplied.
It's about the importance of process over documentation, preparation over punctuation, deal making over contract drafting.
To teach this, since the mid-1990s I've run three hypotheticals on the art of contract negotiation.
The hypothetical are both entertaining and informative. I prepare a script and characterisation for the players. The script allows for a great deal of improvisation. The characters are a panel of "actors" (real people in business playing their real life roles, eg businessperson, lawyer, consultant). The plot involves them talking through a deal in direct negotiations on stage. After many issues arise, this live deal making usually ends in a written contract.
The first and probably best hypothetical I ran was in 1995 for developers of multimedia or IT products at the first national conference of AIMIA. The script had a developer with digital media rights to the book, A History of Australia. The person playing the developer role engaged in negotiations with a panel comprising the book author, book publisher and a CD-ROM distributor. They negotiated together on stage bringing the print book to life on a CD-ROM. DVDs and the internet were not technically or commercially feasible back then.
