OMC is designed to be a large group game. The more people you have, the more chaos! There is no absolute minimum, but in order to get enough chaos going, you will need about 25 people playing.
We love creating OMC tasks and OMC special editions! We would love your input and would be happy to look into creating a new special edition. If you’ve got an idea for one, just email us at firstname.lastname@example.org!
