(English) Nexus Zoo (a scaling simulator)

Including some info about duration of the game (time schedule?) would be helpfull!

Also, instead of “4. step back and let it happen”, I think it would be more fun and a better learning experience if the facilitator acts more as a Product Owner.
Asking questions (communicating with your client / PO) should be encouraged! When no questions are asked, the Product Owner should reject the results because of additional (implicit) requirements, e.g. “the logo should be more business-like”, “the cheetah should be running in the picture because that’s what cheetahs are known for”.
When asked questions about *what* to build the PO should provide sensible answers. Questions about *how* to build or coordinate should not be answered.
